Titan 1.0 Gremlin 3.01 - How to use ignore case text search with Regex ???

[Vitaly Tarasiuk]

Hi all,

I'm working on Titan 1.0 using Text Regex search with Elastic search 2.X, 

gremlin> Titan.version()
==>1.0.0
gremlin> Gremlin.version()
==>3.0.1-incubating

I wonder how can i use ignore case sensitive with search...

found that prefix at the beggining can solve but it doesn't work !!!!

gremlin>

gremlin>

gremlin> graph.V().has("openPositionTitleXXXX" ,textRegex(".*Web Client.*")).valueMap('openPositionTitleXXXX')

==>[openPositionTitleXXXX:[Web Client Developer]]

==>[openPositionTitleXXXX:[Web Client Developer]]

gremlin>

gremlin>

gremlin>

gremlin> graph.V().has("openPositionTitleXXXX" ,textRegex(".*web Client.*")).valueMap('openPositionTitleXXXX')

gremlin>

gremlin> graph.V().has("openPositionTitleXXXX" ,textRegex("(?i).*web Client.*")).valueMap('openPositionTitleXXXX')

gremlin>

gremlin>

gremlin>

gremlin> graph.V().has("openPositionTitleXXXX" ,textRegex("(?i)Web Client.*")).valueMap('openPositionTitleXXXX')

Please advice

BR,

Vitaly

Hi, 

Saw this link , about the same issue,

https://github.com/thinkaurelius/titan/issues/1112

does it mean that the "ignore case" feature supported only after titan 1.1 ?? 

About your answer , I don't understand why ..., according their docs:

http://s3.thinkaurelius.com/docs/titan/1.0.0/search-predicates.html#_text_predicate

"titanRegex" is using internally Regex , and what i do is pure regex functionality - "(?i)regexPattern".

So i need to process each phrase into lower/uppercase template , a lot of overhead , don't you think ?..

Thanks

Hi,

Lucene do not allow to do it simply, so ES and Titan also.

I think the only way it's to do it yourself.

This query should work :

graph.V().has("openPositionTitleXXXX" ,textRegex(".*[w|W][e|E][b|B] [c|C][l|L][i|I][e|E][n|N][t|T].*")).valueMap('openPositionTitleXXXX')

The Github label probably just means they'd like to get it done for Titan 1.1.

We also manually make our regexes case-insensitive as described by Thomas Prelle, because we use ElasticSearch for our index. If you make an internal Titan index then it'll use Java regexes and (?i) will work, but not for an ES index.
