cts.fieldReference(
   field as String,
   [options as String[]]
) as cts.reference

Summary

Creates a reference to a field value lexicon, for use as a parameter to cts.valueTuples. Since lexicons are implemented with range indexes, this function will throw an exception if the specified range index does not exist.

Parameters
field A field name.
options Options. The default is ().

Options include:

"type=type"
Use the lexicon with the type specified by type (int, unsignedInt, long, unsignedLong, float, double, decimal, dateTime, time, date, gYearMonth, gYear, gMonth, gDay, yearMonthDuration, dayTimeDuration, string, anyURI, point, or long-lat-point)
"collation=URI"
Use the lexicon with the collation specified by URI.
"nullable"
Allow null values in tuples reported from cts:value-tuples when using this lexicon.
"unchecked"
Read the scalar type, collation and coordinate-system info only from the input. Do not check the definition against the context database.
"coordinate-system=name"
Create a reference to an index or lexicon based on the specified coordinate system. Allowed values: "wgs84", "wgs84/double", "raw", "raw/double". Only applicable if the index/lexicon value type is point or long-lat-point.
"precision=value"
Create a reference to an index or lexicon configured with the specified geospatial precision. Allowed values: float and double. Only applicable if the index/lexicon value type is point or long-lat-point. This value takes precedence over the precision implicit in the coordinate system name.

Example

cts.fieldReference("authors",["collation=http://marklogic.com/collation/en"]);
=>
cts.fieldReference("authors",
  ["type=string","collation=http://marklogic.com/collation/en"])
