Re: [Neo4j] Lucene and sorting results
Any luck with this?
2010/7/20 Mattias Persson matt...@neotechnology.com
I copied that org.apache.lucene.Hits class into the lucene-index component,
so it exists there in that package (and has existed there since the birth of
this component). That's the class that LuceneIndex.search uses, not the one
from lucene-core-3 (since it has been removed).
2010/7/20 Andrew Mutz andrew.m...@appfolio.com
I was changing the neo4j-rest server to use the new lucene-index framework
myself, and have been very frustrated with this problem. There seems to
be
a lucene version conflict:
- org.neo4j.index.impl.lucene.LuceneIndex.search() uses
org.apache.lucene.Hits, which was removed in lucene 3.0
- org.neo4j.index.impl.lucene.IndexType.query() seems to assume lucene
version 3.0 (Version.LUCENE_30)
So I can't use lucene 3.0 or above for the first reason, and I need to use
3.0 for the second reason.
How are others able to use this? Am I doing something wrong?
Maybe I should just wait until your changes go in?
Thanks,
Andrew.

Exposing this sorting thingie would require you to add that in the rest
code
as well (as you probably could guess). But the IndexService doesn't
support
querying for more than one property at a time.
However, there's a new indexing framework in the making over at
https://svn.neo4j.org/laboratory/components/lucene-index/ which allows
you
to do these types of queries. This new framework will probably make its
way
into trunk rather soon and eventually replace the indexing found in
neo4j-index component today.
So the answer is no if you use neo4j-index component (which REST does).
But
it's yes if REST were to use the new framework instead. I'll commit the
additions regarding sorting and all that soon (I'm laborating with it
a.t.m.). You could f.ex. ask a query like:
for ( Node node : myTitleIndex.query(
new QueryContext( +title:foo* description:bar ).sort(
Sort.RELEVANCE ) ) {}

Hi all,
I've been evaluating using Neo4J for a project at my company and have
been
consistently impressed with it's capabilities. There is one thing I
need
to
do, however, that I'm not sure is possible.
I'm using the Neo4J REST server. I've been using lucene full text
indexing/searching on my node attributes with great success.
What I want to be able to do is to adjust the relevancy of the results
returned by lucene based on attributes *other* than the one I'm
searching
on.
Example: Nodes have attributes title and description. I want to
search
for
all nodes, say, whose title matches foo*, but have whether or not
description matches bar* affect the order of the search results.
Is this possible? I'm very comfortable getting my hands dirty in the
source, so if this is going to require some hacking, just point me in
the
right direction. I've been extensively modifying the REST server to
fit
my
needs, so ideally my changes would be in that part of the code base.
But
I'm willing to dig deeper if necessary.
Thanks much,
Andrew.
