This piece of work was added by Chris and it's quite complicated. If you feel there's a bug, please elaborate as much as possible, reproduce it and open a Jira ticket. We as a community will be able to help and possibly you will be able to make a contribution :) Cheers -------------------------- *Alessandro Benedetti* Director @ Sease Ltd. *Apache Lucene/Solr Committer* *Apache Solr PMC Member* e-mail: a.benede...@sease.io *Sease* - Information Retrieval Applied Consulting | Training | Open Source Website: Sease.io <http://sease.io/> LinkedIn <https://linkedin.com/company/sease-ltd> | Twitter <https://twitter.com/seaseltd> | Youtube <https://www.youtube.com/channel/UCDx86ZKLYNpI3gzMercM7BQ> | Github <https://github.com/seaseltd> On Mon, 6 Jan 2025 at 20:16, Yue Yu <yue...@bloomreach.com> wrote: > Hi All, > > I see there is a fix for KnnQParser to add selected fqs as pre-filter: > https://issues.apache.org/jira/browse/SOLR-16858 > Chris Hostetter was using "multiselect faceting" as an example to > illustrate the use case. > > However the "multiselect faceting" is still not working well with vector > search: > > In *org/apache/solr/request/SimpleFacets.java* > > protected DocSet computeDocSet(DocSet baseDocSet, List<String> > excludeTagList) > throws SyntaxError, IOException { > ... > > // add the base query > if (!excludeSet.containsKey(rb.getQuery())) { > qlist.add(rb.getQuery()); > } > > ... > } > > Here the base query returned by *rb.getQuery() *still contains all the fqs > as pre-filter including the fq that the facet request tries to exclude. > > I'm wondering if this is fixed in a later version? > > Best, > > Yue >
