> LARQ currently uses Lucene, we could do the same with/for Solr (http://lucene.apache.org/solr/) or ElasticSearch (http://www.elasticsearch.com/).
> Examples, as proof of concept, are here:
>  - https://github.com/castagna/SARQ
>  - https://github.com/castagna/EARQ
> In particular, have a look at IndexBuilder and IndexSearcher interfaces:
>  - https://github.com/castagna/EARQ/blob/master/src/main/java/org/openjena/earq/IndexBuilder.java
>  - https://github.com/castagna/EARQ/blob/master/src/main/java/org/openjena/earq/IndexSearcher.java
> And implementations for Lucene, Solr and ElasticSearch in the corresponding packages:
>  - https://github.com/castagna/EARQ/tree/master/src/main/java/org/openjena/earq/builders
>  - https://github.com/castagna/EARQ/tree/master/src/main/java/org/openjena/earq/searchers
> If we do this, plugging in a different index becomes very easy.
