cts.boostQuery( matching-query as cts.query, boosting-query as cts.query ) as cts.boostQuery
Summary
Returns a query specifying that matches to $matching-query
should have their search relevance scores boosted if they also match
$boosting-query.
| Parameters | |
|---|---|
| matching-query | A sub-query that is used for match and scoring. |
| boosting-query | A sub-query that is used only for boosting score. |
Usage Notes
When used in a search, $boosting-query is not evaluated
if there are no matches to $matching-query.
When used in a search, all matches to $matching-query
are included in the search results. $boosting-query
only contributes to search relevances scores. Scoring is done the same
way as for a cts.andQuery.
