CanonicalFilter
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
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

Session
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.
