Condition boost specifications. If a suggestion matches multiple conditions in the specifications, boost values from these specifications are all applied and combined in a non-linear way. Maximum number of specifications is 20.
Note: Currently only support language condition boost.
ConditionBoostSpec
Boost applies to suggestions which match a condition.
JSON representation
{"condition": string,"boost": number}
Fields
condition
string
An expression which specifies a boost condition. The syntax is the same as filter expression syntax. Currently, the only supported condition is a list of BCP-47 lang codes.
Example:
To boost suggestions in languages en or fr: (lang_code: ANY("en", "fr"))
boost
number
Strength of the boost, which should be in [-1, 1]. Negative boost means demotion. Default is 0.0.
Setting to 1.0 gives the suggestions a big promotion. However, it does not necessarily mean that the top result will be a boosted suggestion.
Setting to -1.0 gives the suggestions a big demotion. However, other suggestions that are relevant might still be shown.
Setting to 0.0 means no boost applied. The boosting condition is ignored.
