Well when I want to do some query on my lucene index, I found a problem:
+(title:a^4.0) +((+type:restaurant +city:CA) (-type:restaurant))
I just want to restrict results that city is not CA and type is restaurant.
But lucene give me a result just that:
+(+type:restaurant +city:CA) and ignore (-type:restaurant )
Can you tell me what’s wrong?
While I do not get exactly what you want, you are probably asking about Boolean Lucene query syntax. I believe Hossman’s blog post about Boolean queries may help you.
