Returns
  • (::String) — The branch resource name, such as projects/*/locations/global/collections/default_collection/dataStores/default_data_store/branches/0.

    Use default_branch as the branch ID or leave this field empty, to search documents under the default branch.

#branch=

#canonical_filter

def canonical_filter() -> ::String
Returns
  • (::String) — The default filter that is applied when a user performs a search without checking any filters on the search page.

    The filter applied to every search request when quality improvement such as query expansion is needed. In the case a query does not have a sufficient amount of results this filter will be used to determine whether or not to enable the query expansion flow. The original filter will still be used for the query expanded search. This field is strongly recommended to achieve high search quality.

    For more information about filter syntax, see SearchRequest.filter.

#filter

def filter() -> ::String
Returns
  • (::String) — The filter syntax consists of an expression language for constructing a predicate from one or more fields of the documents being filtered. Filter expression is case-sensitive.

    If this field is unrecognizable, an INVALID_ARGUMENT is returned.

    Filtering in Vertex AI Search is done by mapping the LHS filter key to a key property defined in the Vertex AI Search backend -- this mapping is defined by the customer in their schema. For example a media customer might have a field 'name' in their schema. In this case the filter would look like this: filter --> name:'ANY("king kong")'

    For more information about filtering including syntax and filter operators, see Filter

#session

def session() -> ::String
Returns
  • (::String) — The session resource name. Optional.

    Session allows users to do multi-turn /search API calls or coordination between /search API calls and /answer API calls.

    Example #1 (multi-turn /search API calls):

    1. Call /search API with the auto-session mode (see below).
    2. Call /search API with the session ID generated in the first call. Here, the previous search query gets considered in query standing. I.e., if the first query is "How did Alphabet do in 2022?" and the current query is "How about 2023?", the current query will be interpreted as "How did Alphabet do in 2023?".

    Example #2 (coordination between /search API calls and /answer API calls):

    1. Call /search API with the auto-session mode (see below).
    2. Call /answer API with the session ID generated in the first call. Here, the answer generation happens in the context of the search results from the first search call.

    Auto-session mode: when projects/.../sessions/- is used, a new session gets automatically created. Otherwise, users can use the create-session API to create a session manually.

    Multi-turn Search feature is currently at private GA stage. Please use v1alpha or v1beta version instead before we launch this feature to public GA. Or ask for allowlisting through Google Support team.
