Ask HN: Distributed lucene implementation

3 points·ameyamk··2 comments

Any good pointer/ analysis on how to implement distributed search using Lucene? Other information on how lucene works, and information about its scoring algorithm would be useful. Also any advice on good programming/ algorithm related blogs would be awesome as well

I don't understand your problem, but you may be interested in investigating the existing solutions:

- cluster of solr servers (but it basically means different indexes composed at query time, so scoring will be affected depending on how you shard, at least last time I checked)

- katta, a platform for serving large lucene indexes

- lucandra, a reimplementation of the Index(Writer|Reader) classes of lucene over cassandra (and of solr)

- lucene-on-cassandra, implementing only the Directory interface over Cassandra

- lucene over distributed memory(terracotta) or grids (gigaspaces, elasticsearch)

but once again, I have no idea of what your problem is so I don't know what you may want.

Basically I'd say the problem boils down on implementing the index in a distributed way if you want scoring consistent with the normal lucene, or just sharding/querying different indexes and reconciling the results if you can live without distributed tf/idf

No specific problem actually, was just trying to learn and understand, what if some one wants to implement large scale search system using lucene how one should go about it. Also, all those options above look interesting, but I am also interested in what sort of thinking/ analysis should be done before you make a decision. In nutshell, I was looking for case studies/ blogs talking about implementing lucene in a distributed fashion. But thanks for your pointers.
