Properties

HasSearchResultPersistenceCount

public bool HasSearchResultPersistenceCount { get; }

Gets whether the "search_result_persistence_count" field is set

Property Value
Type Description
bool

QueryId

public string QueryId { get; set; }

If set, the search result gets stored to the "turn" specified by this query ID.

Example: Let's say the session looks like this: session { name: ".../sessions/xxx" turns { query { text: "What is foo?" query_id: ".../questions/yyy" } answer: "Foo is ..." } turns { query { text: "How about bar then?" query_id: ".../questions/zzz" } } }

The user can call /search API with a request like this:

session: ".../sessions/xxx" session_spec { query_id: ".../questions/zzz" }

Then, the API stores the search result, associated with the last turn. The stored search result can be used by a subsequent /answer API call (with the session ID and the query ID specified). Also, it is possible to call /search and /answer in parallel with the same session ID & query ID.

Property Value
Type Description
string

SearchResultPersistenceCount

public int SearchResultPersistenceCount { get; set; }

The number of top search results to persist. The persisted search results can be used for the subsequent /answer api call.

This field is simliar to the summary_result_count field in [SearchRequest.ContentSearchSpec.SummarySpec.summary_result_count][google.cloud.discoveryengine.v1.SearchRequest.ContentSearchSpec.SummarySpec.summary_result_count].

At most 10 results for documents mode, or 50 for chunks mode.
