TuplesSearch.where
TuplesSearch.where( queries as cts.query ) as TuplesSearch
Summary
Specifies which documents have the co-occurring values. Omit the where() clause to retrieve co-occurring values from all documents in the specified indexes or lexicons.
| 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.tuples.
You can optionally follow it with "clauses" such as orderBy
slice, or map. Results are not
generated until you call Tuples.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.
