Subject RE: Reduce QueryComponent prepare time
Date Mon, 19 Nov 2012 11:08:52 GMT
I'd also like to know which parts of the entire query constitute the prepare time and if it
would matter significantly if we extend the edismax plugin and hardcode the parameters we
pass into (reusable) objects.

> Hi,
> We're seeing high prepare times for the QueryComponent, obviously due to the vast amount
of field and queries. It's common to have a prepare time of 70-80ms while the process times
drop significantly due to warmed searchers, OS cache etc. The prepare time is a recurring
issue and i'd hope if there are people here that can share some thoughts or hints.

no IO issue) and edismax on about a hundred different fields, this includes phrase searches
over most of those fields and SpanFirst queries on about 25 fields.  We'd like to see how
we can avoid doing the same prepare procedure over and over again ;)
