I want to search only Google Maps tags and exclude "Android"
I wish to help out in answering googlemaps
questions because I work with Google Maps in the Brazilian metro system.
From reading the advanced search options, and extrapolating off of the +
referring to a guaranteed match for a tag, you can use a search like [google-maps] -[android]
to search for questions that are tagged google-maps and not with android.
In general, you can use -
to negate something in a search, whether it's a tag, a phrase, or anything.
