Reference documentation and code samples for the Discovery Engine v1 API class SearchRequest.Types.ContentSearchSpec.Types.ExtractiveContentSpec.
A specification for configuring the extractive content in a search
response.
The maximum number of extractive answers returned in each search
result.
An extractive answer is a verbatim answer extracted from the original
document, which provides a precise and contextually relevant answer to
the search query.
If the number of matching answers is less than the
max_extractive_answer_count, return all of the answers. Otherwise,
return the max_extractive_answer_count.
At most five answers are returned for each
[SearchResult][google.cloud.discoveryengine.v1.SearchResponse.SearchResult].
public int MaxExtractiveSegmentCount { get; set; }
The max number of extractive segments returned in each search result.
Only applied if the
[DataStore][google.cloud.discoveryengine.v1.DataStore] is set to
[DataStore.ContentConfig.CONTENT_REQUIRED][google.cloud.discoveryengine.v1.DataStore.ContentConfig.CONTENT_REQUIRED]
or
[DataStore.solution_types][google.cloud.discoveryengine.v1.DataStore.solution_types]
is
[SOLUTION_TYPE_CHAT][google.cloud.discoveryengine.v1.SolutionType.SOLUTION_TYPE_CHAT].
An extractive segment is a text segment extracted from the original
document that is relevant to the search query, and, in general, more
verbose than an extractive answer. The segment could then be used as
input for LLMs to generate summaries and answers.
If the number of matching segments is less than
max_extractive_segment_count, return all of the segments. Otherwise,
return the max_extractive_segment_count.
Specifies whether to also include the adjacent from each selected
segments.
Return at most num_previous_segments segments before each selected
segments.
public bool ReturnExtractiveSegmentScore { get; set; }
Specifies whether to return the confidence score from the extractive
segments in each search result. This feature is available only for new
or allowlisted data stores. To allowlist your data store,
contact your Customer Engineer. The default value is false.
