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.
An expression which specifies a boost condition. The syntax and
supported fields are the same as a filter expression. See
