I wonder if it could fall back to auto-unescape if it sees '%' and can't find any messages, or use an OR query.

So it's now trying the query as-is first, then retrying the unescaped query if there's no results: ------8<------ Subject: [PATCH] searchview: retry queries if uri_unescape-able MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is possible to have double-escaped queries when copy and pasting into browsers, so try to help users work around this common error by automatically retrying after unescaping once.
