how SOLR-savvy you are, so pardon if this is something you already know. But lots of people trip up over the "string" field type, which is NOT tokenized. You usually want "text" unless it's some sort of ID.... So it might be worth it to do some searching earlier rather than later <G>....
Why would you want to tokenize a yyyy-mm-dd value?
I'm liking the 'string' type. If you do yyyy-mm-dd, then you can even sort properly, and range query with endpoints also specified as yyyy-mm-dd, no?
Okay, I'll stop spamming the thread now, heh. Jonathan
