I am trying to create a query, that first will return a set of results, then
it will give a boost to the results that have all the keyword entered by the
user.

This is certainly not expected.
Can you turn on IndexWriter's infoStream and post the result?

Hi,
I'm trying to use Lucene to query a domain that has the following structure

I think what you're asking is how to use SpanNearQuery's without specifying the

Qsol does this by using SpanQuerys. First you inject special marker tokens

If you compiled the code against the same JAR file like you run it, you
*cannot* get this error. Does the code compile (I see no error).
In my opinion, you have somewhere a really old Lucene version in your
classpath (e.g. the exclipse bundled one or something like that).

Hi ba3,
Did you read the Lucid Imagination article I linked to?:
http://www.lucidimagination.com/blog/2009/07/18/the-spanquery/
It has examples, including specifying the term indicating the end of the span.
If the article doesn't do it for you, I need more information to be able to
help.
This exception happened in the two versions (2.4.1 and 2.9).
The code is this:

So whats your problem now: You get this error with 2.9 or 2.4.1? 2.9 is
backwards compatible and also supports FSDir.getDirectory(), too.

I don't have the .jar of other lucene version.
But, in a moment I used the code of the lucene 2.9dev, that is at the svn,
in my classpath. And after I return to use the lucene-core-2.4.1.jar.
With the code of the svn, I did other code to get the Directory instance,
and it was work.
The code follow
If you use Lucene 2.9 (you mentioned this), you can now use
NumericRangeQuery and NumericField for fast range queries. The only problem
is, that QueryParser does not support it (because we have no schema support
and so query parser has no idea which type the field is -- but the new one

If I recall it correctly this method was introduced in Lucene 2.1. I
agree with Ian you must have a different lucene version in your
classpath. Maybe you added the jar to the JDK's / JRE's ext directory
or some other obscure place?!

You've probably got some other version of lucene somewhere in the
classpath, one that doesn't have that method in that class. It is
there in 2.4.1, wasn't there in 1.4.3, so no doubt appeared somewhere
in between. And is deprecated in 2.9-dev.

When you say "using Luke", you're also using a particular analyzer. I forget
which one Luke defaults to, but it may well be stripping out your
special characters.
It's all about your analyzer, and I'm 90% certain you're using one that
strips out these characters when *querying*. You can make Luke
It Depends (tm). The thing to understand is that Lucene is a search*engine*,
not an out-of-the-box product. There are products that do many
of the things you're asking about that are *built* with Lucene, but it's
a more complicated process than just installing it and twiddling
a few configurations.

Right, what's happening here is the ConcurrentMergeScheduler, which

Hi everybody,
we just recently upgraded to lucene 2.9 nightly build, since we needed some of
the comparator fixes. We got ooms with some ScoreDocComparators which are now
replaced with FieldComparators.
I refactored the usages of deprecated apis and changed only small things.
