------------------------------------
Summary: Implement pre-filtering functionallity for KnnQParser
Key: SOLR-16246
URL: https://issues.apache.org/jira/browse/SOLR-16246
Project: Solr
Issue Type: Task
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Elia Porciani
At the current state of development, with KnnQParser it is possible to specify
filter queries and the result is the intersection between:
* top-K document founds by the KNN search
* Results of the filter query
As a consequence, if the filter query filters out some documents in the top-K
results, we will have less than K results in the result set.
The proposal is to leverage the recent Apache Lucene development
[LUCENE-10382|https://issues.apache.org/jira/browse/LUCENE-10382] to change the
behavior of the filter queries in the KnnQParser in such a way:
* The filter query works as pre-filtering
* KNN Search retrieves the top-K results among the documents that are not
filtered out.
