Mike cheers for the reply.
Is it worth setting up your own caching or letting the OS do it? I've setup
a caching system, but if the OS is doing it it seems pointless.

Yes and no. I extended the QueryParser and overrode the getRangeQuery method

No, Lucene doesn't. But the OS usually does (in is IO cache),
assuming there is spare RAM.
The "only" things that are explicitly held in memory by Lucene are the
norms ("boost bytes"), terms dict index, deletions bit vector and
field cache (used eg when you sort by a field), I think.

You might also want to think about which analyzer you're using
for this field then. KeywordAnalyzer may suit your purpose if
you're using some other one, or possibly even WhitespaceAnalyzer.
PerFieldAnalyzeWrapper may be your friend too

That works, and now that I re-test my original code, it also works.

If you're thinking about sharding etc, have you looked at SOLR which
manages a lot of the hard stuff for you?

Hi, I have indexed the following two fields:
org_id - NOT_ANALYZEDorg_name - ANALYZED
However when I try to search by org_id, for example, 12345, I get no hits.
I am using the StandardAnalyzer to index and search.
And I am using: Query query = queryParser.parse("org_id:12345");
Any ideas? Th
Thanks Erick,
I don't have any access control constraints. The index won't be exposed to
the users. I am just concerned about scalability issues. I'll probably use
adding a user identifier field approach first and I'll try sharding based on
that value when my index grows.

I am sorry, I dont understand what you are trying to say. Its confusing to me.
If you want a Fuzzy query, where the first 3 chars ("the") always match (a
PrefixQuery) and the rest of the term is fuzzy, use this Constructor and pass 3
as prefixlen:
http://lucene.apache.org/java/3_0_1/api/all/org
Update to my last response with a sample of what I thought you might mean:
This does not work.
Original query up till now:
+(item.name:the* item.name:the)
New query would look like this (which states
Match item.name where a term exists that is either
Exactly the or starts with the):
+(item.name:t
Thanx.
However I do not fully understand, specifically with "how many characters
are the prefix".
As far as I understand you tell the prefix query
How fuzzy the search shall be. In my example below
0.79 means 4 out of 5 characters must match.
Do you mean I should change code to this:
BooleanQuer
Hi everybody:
I have a big problem with solr in a server with the memory size it is using,
I would want to know how to configure it to use a limited memory size, I am
setting up Solr with "java -jar start.jar" command in an ubuntu server, the
process start.jar is using 7Gb of memory in the server
Dont use PrefixQuery, only FuzzyQuery. There you pass in the whole term (with
prefix) and define how many characters are the prefix.

Well, how would this look like in code?
Currently I have the prefix query like this:
BooleanQuery bQuery = new BooleanQuery();
PrefixQuery prefixQuery = new PrefixQuery(new Term("item.name", termText));
bQuery.add( prefixQuery, Occur.MUST);
I dont see any class named PrefixTerm.
I'd appreciate it
How about a fuzzy query with a prefix term? Its configureable.

Hello.
Is it possible to combine PrefixQuery and FuzzyQuery?
The search on a term should both be fuzzy but also match with results that
jut begin with that token (or an approximation of that token).
If it is possible, can you give me an example on how to achieve this?
Currently I only use the Pr

Well... you are 50% right.
when you write
*
*
* Query q = qp.parse("\"united states\"");*
It does search for two separate tokens "united" and "states" but checks if
those are written sequentially. So above search will search for documents
where token "states" is written after "united".
*Note* th
Does a token of "united states" exist in index if using standard analyzer.
My understanding is, united and states are separately stored in index, but
not as "united states". So, if I build a query like Query q =
qp.parse("\"united states\""); It would not return any result. Am I right?
