MarkLogic 9 Product DocumentationWordsSearch.where
WordsSearch.where( queries as cts.query ) as WordsSearch
Summary
Limit the words returned by a word lexicon query to those in documents selected by a query.
| Parameters | |
|---|---|
| queries | One or an array of cts.query objects matching documents. Some helper functions such as cts.parse() and jsearch.byExample() return a cts.query object. |
Usage Notes
Apply this method only to the output from jsearch.words.
You can construct the input queries using cts.parse,
jsearch.byExample, a cts.query constructor such as
cts.jsonPropertyWordQuery or
cts.elementValueQuery, or any other function that
returns a cts.query object.
Omit the where clause to retrieve words from all documents.
