Another quick bug fix.
- Fixed the Did you mean -feature, which was broken by the database change.
- WordPress doesn’t support searching for multiple categories with the cat query variable. There’s now new cats, which can take multiple categories as a comma-separated list.
For some reason, WordPress doesn’t take arguments like ?s=term&cat=1,2 but strips the ‘,2’. Now you can just say ?s=term&cats=1,2 and it’ll work like a charm.
