|

|
|
Returns documents matching a `positive` query while reducing the
|
|
<<query-filter-context, relevance score>> of documents that also match a
|
|
`negative` query.
|
|
|
|
You can use the `boosting` query to demote certain documents without
|
|
excluding them from the search results.

==== Top-level parameters for `boosting`

Query you wish to run. Any returned documents must match this query.
|
|
|
|
`negative` (Required)::

|
|
Query used to decrease the <<query-filter-context, relevance score>> of matching
|
|
documents.
|
|
|
|
If a returned document matches the `positive` query and this query, the
|
|
`boosting` query calculates the final <<query-filter-context, relevance score>>
|
|
for the document as follows:
|
|
|
|
. Take the original relevance score from the `positive` query.
|
|
. Multiply the score by the `negative_boost` value.
|
|
--
|
|
|
|
`negative_boost` (Required)::
|
|
Floating point number between `0` and `1.0` used to decrease the
|
|
<<query-filter-context, relevance scores>> of documents matching the `negative`
|
|
query. |
