Subject Re: Message via your Google Profile: Lucene limits
Date Sun, 02 Jun 2013 20:56:59 GMT
I am trying to implement Lucene on high volume. We implemented Lucene 4.1,
The search with Facets is very slow and consume high amount of RAM and
cause Swapping. We have 7gb of index, it includes 70 millions of Documents
(pretty short doc). The Search (inc. Facets) takes 30-60 seconds which is
way too long for our needs. We ran it on x3550 (Intel) server , 12gb. We
have other processes running on the same machine. Is it reasonable? is it
realistic to expect 1-3 seconds search of both hits and facets (we have 7-8
facets)? in some cases the number of hits is 50Millions or so. Thank you,
hope it is okay to email you this question.
We are using Lucene (not Solr -- I don't know why; we will review moving to
Solr soon).
We are allocating 4-6 gb for Java maximum (we wish we could limit it to 2-3
gb max or for short time).
