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")'
