Attributes |
|
|---|---|
| Name | Description |
max_return_results |
int
Number of search results to return. The default value is 10. |
filter |
str
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. This will be used to filter search results which may affect the Answer response. 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 customers might have a field
'name' in their schema. In this case the filter would look
like this: filter --> name:'ANY("king kong")'
