This package doesn't have In operator

[mhdprogrammer]

As you know "IN" operator is one of the important operator in AQL, but I can't find it in your Linq queries.
Example:
For doc in User
Filter doc.Username IN ["a","b","c"] // this In operator
return doc

Thank you

["a", "b"].Contains(x.Username)

[mhdprogrammer]

But if you convert this to AQL, you can see this isn't an "IN" operator, contains method is converted to Position function in AQL.
I need to "IN", because when we use this operator arangodb use Index of the collection, but when we use Position function or contains function it doesn't use Index.

For doc in User
Filter doc.Username in ["a", "b"]//Use Username index
Return doc

For doc in User
Filter Position(["a", "b"], doc.Username) //doesn't use Username Index
Return doc
