Boost applies to products which match a condition.
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 item a big promotion. However, it does not
necessarily mean that the boosted item will be the top result at all
times, nor that other items 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 items.
Setting to -1.0 gives the item a big demotion. However, results that
are deeply relevant might still be shown. The item 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
[SearchRequest.filter][google.cloud.retail.v2.SearchRequest.filter] for
detail syntax and limitations.
Examples:
To boost products with product ID "product_1" or "product_2", and
color
"Red" or "Blue":
(id: ANY("product_1", "product_2")) AND (colorFamilies:
ANY("Red","Blue"))
