"lexicon-expand=value" The value is one of full, prefix-postfix, off, or heuristic (the default is heuristic). An option with a value of lexicon-expand=full specifies that wildcards are resolved by expanding the pattern to words in a lexicon (if there is one available), and turning into a series of cts:word-queries, even if this takes a long time to evaluate. An option with a value of lexicon-expand=prefix-postfix specifies that wildcards are resolved by expanding the pattern to the pre- and postfixes of the words in the word lexicon (if there is one), and turning the query into a series of character queries, even if it takes a long time to evaluate. An option with a value of lexicon-expand=off specifies that wildcards are only resolved by looking up character patterns in the search pattern index, not in the lexicon. An option with a value of lexicon-expand=heuristic, which is the default, specifies that wildcards are resolved by using a series of internal rules, such as estimating the number of lexicon entries that need to be scanned, seeing if the estimate crosses certain thresholds, and (if appropriate), using another way besides lexicon expansion to resolve the query. * "lexicon-expansion-limit=number" Specifies the limit for lexicon expansion. This puts a restriction on the number of lexicon expansions that can be performed. If the limit is exceeded, the server may raise an error depending on whether the "limit-check" option is set. The default value for this option will be 4096. "limit-check" Specifies that an error will be raised if the lexicon expansion exceeds the specified limit. "no-limit-check" Specifies that error will not be raised if the lexicon expansion exceeds the specified limit. The server will try to resolve the wildcard.
weight XsDouble <optional>
A weight for this query. Higher weights move search results up in the relevance order. The default is 1.0. The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. Weights less than the absolute value of 0.0625 (between -0.0625 and 0.0625) are rounded to 0, which means that they do not contribute to the score.

Parameters:
Name Type Argument Description
elementName XsQName <optional>
One or more element QNames to match. When multiple QNames are specified, the query matches if any QName matches.
text XsString <optional>
Some words or phrases to match. When multiple strings are specified, the query matches if any string matches.
options XsString <optional>
Options to this query. The default is (). Options include: "case-sensitive" A case-sensitive query. "case-insensitive" A case-insensitive query. "diacritic-sensitive" A diacritic-sensitive query.

The iso639code code portion is case-insensitive, and uses the languages specified by ISO 639. The default is specified in the database configuration. "distance-weight=number" A weight applied based on the minimum distance between matches of this query. Higher weights add to the importance of proximity (as opposed to term matches) when the relevance order is calculated. The default value is 0.0 (no impact of proximity). The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. This parameter has no effect if the word positions index is not enabled. This parameter has no effect on searches that use score-simple, score-random, or score-zero (because those scoring algorithms do not consider term frequency, proximity is irrelevant). "min-occurs=number" Specifies the minimum number of occurrences required. If fewer that this number of words occur, the fragment does not match. The default is 1. "max-occurs=number" Specifies the maximum number of occurrences required. If more than this number of words occur, the fragment does not match. The default is unbounded. "synonym" Specifies that all of the terms in the $text parameter are considered synonyms for scoring purposes.

"lexicon-expand=value" The value is one of full, prefix-postfix, off, or heuristic (the default is heuristic). An option with a value of lexicon-expand=full specifies that wildcards are resolved by expanding the pattern to words in a lexicon (if there is one available), and turning into a series of cts:word-queries, even if this takes a long time to evaluate. An option with a value of lexicon-expand=prefix-postfix specifies that wildcards are resolved by expanding the pattern to the pre- and postfixes of the words in the word lexicon (if there is one), and turning the query into a series of character queries, even if it takes a long time to evaluate. An option with a value of lexicon-expand=off specifies that wildcards are only resolved by looking up character patterns in the search pattern index, not in the lexicon. An option with a value of lexicon-expand=heuristic, which is the default, specifies that wildcards are resolved by using a series of internal rules, such as estimating the number of lexicon entries that need to be scanned, seeing if the estimate crosses certain thresholds, and (if appropriate), using another way besides lexicon expansion to resolve the query. * "lexicon-expansion-limit=number" Specifies the limit for lexicon expansion. This puts a restriction on the number of lexicon expansions that can be performed. If the limit is exceeded, the server may raise an error depending on whether the "limit-check" option is set. The default value for this option will be 4096. "limit-check" Specifies that an error will be raised if the lexicon expansion exceeds the specified limit. "no-limit-check" Specifies that error will not be raised if the lexicon expansion exceeds the specified limit. The server will try to resolve the wildcard.
weight XsDouble <optional>
A weight for this query. Higher weights move search results up in the relevance order. The default is 1.0. The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. Weights less than the absolute value of 0.0625 (between -0.0625 and 0.0625) are rounded to 0, which means that they do not contribute to the score.

jsonPropertyChildGeospatialQuery(parentPropertyName, childPropertyNames, regions, options, weight) → {CtsQuery}

Returns a cts:query matching json properties by name which has specific children representing latitude and longitude values for a point contained within the given geographic box, circle, or polygon, or equal to the given point. Points that lie between the southern boundary and the northern boundary of a box, travelling northwards, and between the western boundary and the eastern boundary of the box, travelling eastwards, will match. Points contained within the given radius of the center point of a circle will match, using the curved distance on the surface of the Earth. Points contained within the given polygon will match, using great circle arcs over a spherical model of the Earth as edges. An error may result if the polygon is malformed in some way. Points equal to the a given point will match, taking into account the fact that longitudes converge at the poles.

Returns a query matching JSON properties by name with text content containing a given phrase. Searches only through immediate text node children of the specified property. Provides a client interface to a server function. See cts.jsonPropertyWordQuery
Parameters:
Name Type Argument Description
propertyName XsString <optional>
One or more JSON property names to match. When multiple names are specified, the query matches if any name matches.
text XsString <optional>
Some words or phrases to match. When multiple strings are specified, the query matches if any string matches.
options XsString <optional>
Options to this query. The default is (). Options include: "case-sensitive" A case-sensitive query. "case-insensitive" A case-insensitive query. "diacritic-sensitive" A diacritic-sensitive query. "diacritic-insensitive" A diacritic-insensitive query. "punctuation-sensitive" A punctuation-sensitive query. "punctuation-insensitive" A punctuation-insensitive query.

Shorthand for "case-sensitive", "diacritic-sensitive", "punctuation-sensitive", "whitespace-sensitive", "unstemmed", and "unwildcarded". "lang=iso639code" Specifies the language of the query. The iso639code code portion is case-insensitive, and uses the languages specified by ISO 639. The default is specified in the database configuration. "distance-weight=number" A weight applied based on the minimum distance between matches of this query. Higher weights add to the importance of proximity (as opposed to term matches) when the relevance order is calculated. The default value is 0.0 (no impact of proximity). The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. This parameter has no effect if the word positions index is not enabled. This parameter has no effect on searches that use score-simple, score-random, or score-zero (because those scoring algorithms do not consider term frequency, proximity is irrelevant). "min-occurs=number" Specifies the minimum number of occurrences required. If fewer that this number of words occur, the fragment does not match. The default is 1. "max-occurs=number" Specifies the maximum number of occurrences required. If more than this number of words occur, the fragment does not match. The default is unbounded. "synonym" Specifies that all of the terms in the $text parameter are considered synonyms for scoring purposes. The result is that occurrences of more than one of the synonyms are scored as if there are more occurrences of the same term (as opposed to having a separate term that contributes to score). "lexicon-expand=value" The value is one of full, prefix-postfix, off, or heuristic (the default is heuristic). An option with a value of lexicon-expand=full specifies that wildcards are resolved by expanding the pattern to words in a lexicon (if there is one available), and turning into a series of cts:word-queries, even if this takes a long time to evaluate. An option with a value of lexicon-expand=prefix-postfix specifies that wildcards are resolved by expanding the pattern to the pre- and postfixes of the words in the word lexicon (if there is one), and turning the query into a series of character queries, even if it takes a long time to evaluate. An option with a value of lexicon-expand=off specifies that wildcards are only resolved by looking up character patterns in the search pattern index, not in the lexicon. An option with a value of lexicon-expand=heuristic, which is the default, specifies that wildcards are resolved by using a series of internal rules, such as estimating the number of lexicon entries that need to be scanned, seeing if the estimate crosses certain thresholds, and (if appropriate), using another way besides lexicon expansion to resolve the query. * "lexicon-expansion-limit=number" Specifies the limit for lexicon expansion. This puts a restriction on the number of lexicon expansions that can be performed. If the limit is exceeded, the server may raise an error depending on whether the "limit-check" option is set. The default value for this option will be 4096. "limit-check" Specifies that an error will be raised if the lexicon expansion exceeds the specified limit. "no-limit-check" Specifies that error will not be raised if the lexicon expansion exceeds the specified limit. The server will try to resolve the wildcard.
weight XsDouble <optional>
A weight for this query. Higher weights move search results up in the relevance order. The default is 1.0. The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. Weights less than the absolute value of 0.0625 (between -0.0625 and 0.0625) are rounded to 0, which means that they do not contribute to the score.

wordQuery(text, options, weight) → {CtsQuery}

Returns a query matching text content containing a given phrase. Provides a client interface to a server function. See cts.wordQuery
Parameters:
Name Type Argument Description
text XsString <optional>
Some words or phrases to match. When multiple strings are specified, the query matches if any string matches.
options XsString <optional>
Options to this query. The default is (). Options include: "case-sensitive" A case-sensitive query. "case-insensitive" A case-insensitive query. "diacritic-sensitive" A diacritic-sensitive query. "diacritic-insensitive" A diacritic-insensitive query. "punctuation-sensitive" A punctuation-sensitive query. "punctuation-insensitive" A punctuation-insensitive query. "whitespace-sensitive" A whitespace-sensitive query. "whitespace-insensitive" A whitespace-insensitive query. "stemmed" A stemmed query. "unstemmed" An unstemmed query.

Shorthand for "case-sensitive", "diacritic-sensitive", "punctuation-sensitive", "whitespace-sensitive", "unstemmed", and "unwildcarded". "lang=iso639code" Specifies the language of the query. The iso639code code portion is case-insensitive, and uses the languages specified by ISO 639. The default is specified in the database configuration. "distance-weight=number" A weight applied based on the minimum distance between matches of this query. Higher weights add to the importance of proximity (as opposed to term matches) when the relevance order is calculated. The default value is 0.0 (no impact of proximity). The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. This parameter has no effect if the word positions index is not enabled. This parameter has no effect on searches that use score-simple, score-random, or score-zero (because those scoring algorithms do not consider term frequency, proximity is irrelevant). "min-occurs=number" Specifies the minimum number of occurrences required. If fewer that this number of words occur, the fragment does not match. The default is 1. "max-occurs=number" Specifies the maximum number of occurrences required. If more than this number of words occur, the fragment does not match. The default is unbounded. "synonym" Specifies that all of the terms in the $text parameter are considered synonyms for scoring purposes. The result is that occurrences of more than one of the synonyms are scored as if there are more occurrences of the same term (as opposed to having a separate term that contributes to score). "lexicon-expand=value" The value is one of full, prefix-postfix, off, or heuristic (the default is heuristic). An option with a value of lexicon-expand=full specifies that wildcards are resolved by expanding the pattern to words in a lexicon (if there is one available), and turning into a series of cts:word-queries, even if this takes a long time to evaluate. An option with a value of lexicon-expand=prefix-postfix specifies that wildcards are resolved by expanding the pattern to the pre- and postfixes of the words in the word lexicon (if there is one), and turning the query into a series of character queries, even if it takes a long time to evaluate. An option with a value of lexicon-expand=off specifies that wildcards are only resolved by looking up character patterns in the search pattern index, not in the lexicon. An option with a value of lexicon-expand=heuristic, which is the default, specifies that wildcards are resolved by using a series of internal rules, such as estimating the number of lexicon entries that need to be scanned, seeing if the estimate crosses certain thresholds, and (if appropriate), using another way besides lexicon expansion to resolve the query. "lexicon-expansion-limit=number" Specifies the limit for lexicon expansion. This puts a restriction on the number of lexicon expansions that can be performed. If the limit is exceeded, the server may raise an error depending on whether the "limit-check" option is set. The default value for this option will be 4096. "limit-check" Specifies that an error will be raised if the lexicon expansion exceeds the specified limit. "no-limit-check" Specifies that error will not be raised if the lexicon expansion exceeds the specified limit. The server will try to resolve the wildcard.
weight XsDouble <optional>
A weight for this query. Higher weights move search results up in the relevance order. The default is 1.0. The weight should be between 64 and -16. Weights greater than 64 will have the same effect as a weight of 64. Weights less than the absolute value of 0.0625 (between -0.0625 and 0.0625) are rounded to 0, which means that they do not contribute to the score.
