Implement branch:foo,bar

[gajus]

name:foo,bar

should be equal to:

name:foo OR branch:bar

[gajus]

Implementing this most likely requires adding a new AST type that represents IN operation. Otherwise, we wouldn't be able to serialize AST back into the original query.

[gajus]

We could also add support for an implicit OR operator, e.g. foo,bar equal to foo OR bar, but that becomes ambiguous in the context of name:foo,bar, i.e., does this mean name:foo OR branch:bar or name:foo OR bar

[gajus]

would name:foo,bar and name:foo, bar be treated differently?

Until there is clarity how to implement this in a way that does not cause ambiguity, it is unlikely to be added.
