To disable interpretation of “simple” indexes (numbers between separators), use schema = schema.withParseSimpleIndexes(false).
I think brackets are used as the default index separator so no further configuration should be needed. If you did want to change them, you would use:

schema = schema.withIndexMarker(Markers.crete("(", ")");

Hope this helps!
