I have a word document, I want to select all the abbreviations in it. I tried to use the `advanced search` and check the `wild card`.
However it doesn't show any results with the following code.

`([\(])([A-Z])([\)]){2,4}`

The abbreviation would look like `Apple tree (APt)`, `All trees (AT)` etc

1. The `(APt)` is the abbreviation, with some letters capital and some are simple. But some will only contain capitals (`(AAA)`) and some only simples (`(mm)`).
2. The abbreviation will always be inside two parenthesis `()`
