Gremlin: Performing Text Search in AWS Neptune

[Srinath Ganesh]

Using Gremlin how can I perform Text search like,

- Name starts with "A"
- Name ends with "B"
- Name contains "t"
- etc.

I know NEO4J and Janus have some custom code for such a thing.

I figured out Neptune does not support Regex. https://forums.aws.amazon.com/thread.jspa?messageID=854392

Here's my answer on SO - https://stackoverflow.com/q/51149370/1831717 - not sure there's much you can do beyond that for right now.

You can precompute these values before storing in graph and apply equality operator while querying

So in your use case, you will have to add three properties to the vertex

NameStartsWithA : bool

NameEndsWithB : bool

NameContainst : bool

While inserting the vertex, you can compute the values of the above properties and store true/false

and you gremlin query can be like

g.V().has('NameStartsWithA',true)

but again, this is not text search and can only search pre decided values
