public override PagedEnumerable<SearchResponse, SearchResponse.Types.SearchResult> SearchLite(SearchRequest request, CallSettings callSettings = null)
Performs a search. Similar to the
[SearchService.Search][google.cloud.discoveryengine.v1.SearchService.Search]
method, but a lite version that allows API key for authentication, where
OAuth and IAM checks are not required.
Only public website search is supported by this method. If data stores and
engines not associated with public website search are specified, a
FAILED_PRECONDITION error is returned.
This method can be used for easy onboarding without having to implement an
authentication backend. However, it is strongly recommended to use
[SearchService.Search][google.cloud.discoveryengine.v1.SearchService.Search]
instead with required OAuth and IAM checks to provide better data security.
