Great initiative, btw have you looked at the LuceneFulltextIndexService in the same package? It might be able to do what you're asking for.
By @Overriding the formQuery method you can construct whatever queries you like based on key and search value (I just altered the signature to also take the key in addition to value for greater flexibility). Please have a look at that first and see if that helps you! Also do an 'svn up' on the index-util component since I committed it just now :) 2009/6/30 Peter Neubauer <neubauer.pe...@gmail.com>: > Adam, > we would love to get your contribution into the codebase, just contact > us regarding the CLA etc and we will get you through it! > > /peter > > GTalk: neubauer.peter > Skype peter.neubauer > Phone +46 704 106975 > LinkedIn http://www.linkedin.com/in/neubauer > Twitter http://twitter.com/peterneubauer > > http://www.neo4j.org - New Energy for Data - The Graph Database. > http://www.ops4j.org - New Energy for OSS Communities - Open > Participation Software. > http://www.oredev.org - Where Good Geeks Grok. > > > > On Tue, Jun 30, 2009 at 10:13 PM, Anders > Nawroth<and...@neotechnology.com> wrote: >> Hi and welcome! >> >> I can't answer your questions, but regarding the formatting we use an >> Eclipse code formatter which you can download from this page: >> http://wiki.neo4j.org/content/Coding_Standard >> >> This page could be of some interest as well: >> http://wiki.neo4j.org/content/Code_Contributor%27s_Guide >> >> /anders >> >> >> Adam Rabung skrev: >>> Hi, >>> I was wondering if anyone's interested in more complex queries against >>> Neo's Lucene (and others) indexes, like so: >>> >>> long twoHoursAgo = System.currentTimeMillis() - (2 * 60 * 60 * 1000); >>> indexService.getNodes(new Comparison("modifiedTime", >>> ComparisonType.GREATER_THAN, twoHoursAgo); >>> >>> I hacked this into my local >>> IndexService/LuceneIndexService/LuceneTransaction, and it seems to >>> work.
