Query like this: WHERE name =~ "Hello"

Merged to tinkerpop334 branch as well.

mad commented 5 years ago

JanusGraph support custom Text.REGEX predicate that can be translated to backend specified query like a lucene RegexpQuery

It may implemented using the GremlinRewriter?

dwitry commented 5 years ago

It would be straightforward to implement using rewriter, however it would require to create separate module in Cypher for Gremlin, because Text is located in janusgraph-core. We try to avoid implementation specific dependencies in Cypher for Gremlin translation module.
