Full text search a-la-titan

Is there a way or plan to get full text search on edge/node properties?

This is needed to support full tinkerpop features (see e.g. titan 
support for this [1])

Thanks for the info and pointers to currently supported predicates.

Aside to hbase, to you plan to use external search engine (e.g. solr) to 
index the full text on every mutation? Another option is the 
hbase-indexer co-processor [1] that update an external solr cluster.

Or maybe you think to use hbase only, but I don't see how to deliver 
text-search capability in an efficient way with hbase only.

PS: Doc is indeed something to work on, but for now, we should better 
concentrate on the implementation

Full text search is not yet supported, but it is good idea to support them.

For anyone who is interested, followings are list of currently supported
predicates.

1. eq: "="
2. neq: "!="
3. gt: ">"
4. gte: ">="
5. lt: "<"
6. lte: "<="
7. in: x in (1, 3, 5)
8. between(a, b): a <= x <= b

We should document this better, but until then see the examples in
org.apache.s2graph.core.parsers.WhereParserTest.scala.
