Hi Ahmet, it works, thanks a lot!
To be true I have no idea what's the problem with defType=lucene&q.op=OR&df=topic&q=R NOT [* TO *] -Sascha Ahmet Arslan wrote:
I have a (multi-valued) field topic in my index which does not need to exist in every document. Now, I'm struggling with formulating a query that returns all documents that either have no topic field at all *or* whose topic field value is R.Does this work? &defType=lucene&q.op=OR&q=topic:R (+*:* -topic:[* TO *])
