Faceting with Solr

After my discussion with Yonik Seeley, one of the Solr developers, I have to come to realize the way I was faceting was not correct. Although it worked, it did not work for speed and scalability. The proper way to query by facets is to use the ‘fq’ field as many times as needed. Each of these result sets is then cached, speeding up the next query as you add more facets. In line with the example I have been posting about, things have many tags, here is an example. When you run this query you will get anything with the phrase ‘stuff’ that is also tagged with ‘things’ and ‘junk’.

q=stuff&rows=10&facet=true&facet.field=tagsFaceted&fq=things&fq=junk
