Fields
queryId

string

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?" queryId: ".../questions/yyy" } answer: "Foo is ..." } turns { query { text: "How about bar then?" queryId: ".../questions/zzz" } } }

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

session: ".../sessions/xxx" sessionSpec { queryId: ".../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.
searchResultPersistenceCount

integer

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

This field is similar to the summaryResultCount field in SearchRequest.ContentSearchSpec.SummarySpec.summary_result_count.

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