I have recently enabled facet.missing=true in solrconfig.xml which gives null facet values also. As I understand it, the syntax to do a faceted search on a null value is something like this: &fq=-price:[* TO *] So when I want to search on a particular value (for example : 4) OR null value, I would expect the syntax to be something like this: &fq=(price:4+OR+(-price:[* TO *])) But this does not work. After searching around for more, read somewhere that the right way to achieve this would be: fq=-(-price:4+AND+price:[*+TO+*]) Now this does work but seems like a very roundabout way. Is there a better way to achieve this ?
Pure negative queries don't work -- you have to have results in the query before you can subtract. For some top-level queries, Solr is able to detect this situation and fix it internally, but on inner queries you must explicitly state your intentions. It is best if you always use '*:* -query' syntax, just to be safe.
fq=(price:4+OR+(*:* -price:[* TO *])) Thanks, Shawn
