=== Boosting Query
|
|
|
|
The `boosting` query can be used to effectively demote results that
|
|
match a given query. Unlike the "NOT" clause in bool query, this still
|
|
selects documents that contain undesirable terms, but reduces their
|
|
overall score.
|
|
|
|
It accepts a `positive` query and a `negative` query.
|
|
Only documents that match the `positive` query will be included
|
|
in the results list, but documents that also match the `negative` query
|
|
will be downgraded by multiplying the original `_score` of the document
|
|
with the `negative_boost`.
