MarkLogic Server 11.0 Product DocumentationValuesSearch.where
ValuesSearch.where( queries as cts.query ) as ValuesSearch
Summary
Specifies which documents have values in the index. Omit the where() clause to retrieve all values in the index.
| 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 to the output from jsearch.values.
You can optionally follow it with "clauses" such as orderBy
slice, or map. Results are not
generated until you call ValuesSearch.result.
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.
