Reference documentation and code samples for the Discovery Engine v1beta API class AdvancedCompleteQueryRequest.Types.BoostSpec.Types.ConditionBoostSpec.
Boost applies to suggestions which match a condition.
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"))
