Strength of the condition boost, which should be in [-1, 1]. Negative
boost means demotion. Default is 0.0.
Setting to 1.0 gives the document a big promotion. However, it does
not necessarily mean that the boosted document will be the top result
at all times, nor that other documents will be excluded. Results
could still be shown even when none of them matches the condition.
And results that are significantly more relevant to the search query
can still trump your heavily favored but irrelevant documents.
Setting to -1.0 gives the document a big demotion. However, results
that are deeply relevant might still be shown. The document will have
an upstream battle to get a fairly high ranking, but it is not
blocked out completely.
Setting to 0.0 means no boost applied. The boosting condition is
ignored. Only one of the (condition, boost) combination or the
boost_control_spec below are set. If both are set then the global boost
is ignored and the more fine-grained boost_control_spec is applied.
An expression which specifies a boost condition. The syntax and
supported fields are the same as a filter expression. See
SearchRequest.filter
for detail syntax and limitations.
Examples:
To boost documents with document ID "doc_1" or "doc_2", and
color "Red" or "Blue":
(document_id: ANY("doc_1", "doc_2")) AND (color: ANY("Red", "Blue"))
