But do we really need to optimize it? I mean, I didn't see it running more than ~20 ms, and with this patch for small queries it runs like ~16 ms. Worst case is when user types something in KRunner, but again, the lag is negligible there.</p></div></div><br /><div><strong>INLINE COMMENTS</strong><div><div style="margin: 6px 0 12px 0;"><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D11828#inline-87138">View Inline</a><span style="color: #4b4d51; font-weight: bold;">orpostingiterator.cpp:73</span></div>

<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">Usage of <tt style="background: #ebebeb; font-size: 13px;">auto</tt> keyword (at least for docId) somehow made it a bit harder to read for me.

(it's fine for iterators, whose definition has a long-long-name and it's clear from the line that it's an iterator. But for ordinary <tt style="background: #ebebeb; font-size: 13px;">docId</tt> I've began to think it's not <tt style="background: #ebebeb; font-size: 13px;">quint64</tt>, but some weird class with large definition or something).</p></div></div><br /><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D11828#inline-87139">View Inline</a><span style="color: #4b4d51; font-weight: bold;">orpostingiterator.cpp:79</span></div>
