@apatry: I ported neo4j-lucene-index to Lucene 4. The result is at https://github.com/apatry/neo4j-lucene4-index.

If I can do anything to help making it go into the distribution, please let me know.

@jakewins: Mate, this is a great initiative, thanks for putting the effort in! I don't know how big of a change this is, but if this is a stable version of lucene, and it does not introduce any breaking changes in the actual lucene queries, we will definitely consider including it. If it is decided to be included, it could be that we wait until Neo4j 1.10, as 1.9 contains large changes to the Neo4j cluster systems, and we may not want to introduce too many other moving parts in that release. Not my call though.

To help the effort, can you verify that all unit and integration tests covering the original implementation pass (run mvn clean install), and with that in place, make sure that all unit and integration tests pass for the other Neo4j components that would use this - including the components in the advanced and enterprise Neo4j repositories?

That would basically mean forking the community repo and introducing this upgrade into the lucene-index project there, running mvn clean install on the community project, and then running the same on advanced and enterprise. Heads up though: We are merging those three repos this week into a single repo called "neo4j", you may want to wait until that is done.

With that, ping @tinwelint or @johan-neo, as they would be the ones to yay or nay a contribution to this part of the code base.

It looks like we will stick with the 3.x branch of lucene for now, but for people wanting the power of Lucene 4.0, this provider is an excellent addition to Neo4j.

Is there a plan to update the lucene version? Are the neo4j 2 schema indexes also using lucene? Is it planned to not use lucene anymore for indexing in the far future?

from neo4j.

@TekTimmy Yes, the schema indexes uses Lucene. We don't have any specific plans for the Lucene integration at the moment. It's still being discussed.
