First of all, I'm not very experienced in using Solr, so I hope this isn't a stupid question ..
I am experiencing some unexpected behavior with a Solr query. Suppose the query is q="Foo:"Bar"
. Now make it q="Foo:"Bar" AND()
and we get more results back, which just seem random and certainly not meeting condition "Foo" = "Bar".
Am I missing something here? It doesn't seem logical that an extra condition would return more results instead of less.
