Tinkerpop [2.6.0] - Solution for loading vertices by property that match a regexp (wildcard)

[Kamen Ivanov]

Hello, Is there any method that can help me load vertices from a given class, that have a property which matches a regexpr (or wildcard like in SQL - name LIKE 'Apu%'). Or I can do this only by using the gremlin or Tinkerpop Pipes?

[Daniel Kuppitz]

The only graph database that supports that is Titan (afaik); it adds the String search predicates REGEX and CONTAINS_REGEX. The only other solution I can think of is a lambda .filter() step in Gremlin (but that's probably what you've already figured out).

Cheers,

Daniel

Thanks for the answer Daniel, i'm sorry for the late response, i was busy at work, I was thinking of that but wasn't sure whether to use .filter() or something else, thanks for the hint, I'll try it tonight.

Have a nice day,

Hi Daniel,

Is it supports this functionality now in CosmosDB?.. Please can you provide the solution. In my case properties will dynamically change.. i have one string "xyz" using that string i want to retrieve all the vertex properties that have string "xyz".

[Daniel Kuppitz]

I don't know, I never tried CosmosDB. Probably not, as I just recently learned that it doesn't even support match(). But I dunno, you'll get a better answer reading the docs I guess.

Cheers,

Daniel
