* apos.get, snippets.get and friends now implement "search" and "autocomplete" options. "search" offers google-like search powered by mongodb and is not for partial word matches. "autocomplete" supports partial matches but only examines titles, tags and other important metadata fields as appropriate to the content being searched. The "q" option has been aliased to "search", and the "titleSearch" option has been aliased to "autocomplete".
