<p dir="auto">Just a suggestion to allow delete by query, especially wildcard queries against the _id, instead of just delete by _id.  It would be much faster and easier than one by one.</p>
<p dir="auto">The error doesn't happen when I delete the queries one by one.</p>
<p dir="auto">It only happens when you delete the percolator index itself for a index.</p>
