Thanks for the pointers.<br><br>I tried to look for runtime query serving performance numbers to no avail. What is the latency range for random queries at a given rate (say 500 QPS) to a index built at a certain (say 5M docs) size, assuming not too many concurrent connections?<br>
<br>I am expecting sub-second but just curious whether it's more 500ms or 100-200ms range.<br><br>Thanks!<br><br>Crystal<br><br><div class="gmail_quote">On Mon, Jan 19, 2009 at 3:33 AM, Olly Betts <span dir="ltr"><<a href="mailto:olly@survex.com">olly@survex.com</a>></span> wrote:<br>

<br>
</div>Flint is documented here:<br>
<br>
<a href="http://trac.xapian.org/wiki/FlintBackend" target="_blank">http://trac.xapian.org/wiki/FlintBackend</a><br>
<br>
The user-visible change in Chert are covered in here (to find them,<br>
search for "chert backend:"):<br>

<br>
That should be complete at present, but there are likely to be further<br>
changes before chert is declared "finished".<br>
<br>
I don't know of any comparisons with Lucene's low level details.<br>
<br>
