Hello, We use Apache Solr 8.8 and are trying to find out ways to reduce recall (and improve precision) for our products. While looking into various options, we came across the “split on whitspace” (sow) parameter, the value for which changes when multi-word synonyms and stopwords come into picture. The concern here though, is, that for query terms that have sow=false by default, we are able to set it to true. But for the terms where sow=true by default (reasons unknown), we are not able to flip it by setting the param to false. IT still remains a term centric search. We also tried setting the uf query in solrconfig.xml. Another point that we need clarification on is ShingleFilterFactory. How does minimum match apply with Shingles in the picture is what we also wanted to learn. Please help us with the same.
Thanks, Rashmeet
