Methods

#boost

def boost() -> ::Float
Returns
  • (::Float) — 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.

#condition

def condition() -> ::String
Returns
  • (::String) —

    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"))

#condition=

def condition=(value) -> ::String
Parameter
  • value (::String) —

    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"))
Returns
