Hi,
I understand what you need now. Currently this is not possible, but I think I can probably make an adjustment to the index table engine to make this work in the upcoming release.
Keep an eye on the next update, it should be out within 7 days. After that, all you need to do is just re-creating the index table, and it should register these types of strings with both parentheses and without them as well.
