-------------------------------------
Summary: KnnQParser is parsing filter queries incorrectly
Key: SOLR-16858
URL: https://issues.apache.org/jira/browse/SOLR-16858
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
The KnnQParser is parsing the filter query which limits the rows considered by
vector is doing this:
{code:java}
private Query getFilterQuery() throws SolrException, SyntaxError {
boolean isSubQuery = recurseCount != 0;
if (!isFilter() && !isSubQuery) {
String[] filterQueries = req.getParams().getParams(CommonParams.FQ);
if (filterQueries != null && filterQueries.length != 0) {
try {
List<Query> filters = QueryUtils.parseFilterQueries(req);
SolrIndexSearcher.ProcessedFilter processedFilter =
req.getSearcher().getProcessedFilter(filters);
return processedFilter.filter;
{code:java}
// Some comments here
public String getFoo()
{
return foo;
}
{code}
} catch (IOException e) {
throw new SolrException(SolrException.ErrorCode.SERVER_ERROR, e);
}
}
}
return null;
}
{code}
I don't believe this is the behavior we actually want. What we want is to add
an "fq" to the local params of the Knn vector search. Here is the example
syntax:
{code:java}
{!knn f=vector topK=10 fq=$kfq}[...]&kfq=myquery
{code}
