Hi,
The plugin can and does search special characters, it does not treat them separately. The main issue with the apostrophes is, that there is many different types of them. For example, if I search for:
risico’s
.. I am getting more results when I search for:
risico's
..only because the first type of apostrophe is used in the articles, not the second one.
One way to treat these is to simply replace them with empty strings, you can do that on the search back-end: https://i.imgur.com/QMxrEGG.png
I have added these items in the screenshot: ',",’
The search with the parentheses seemed to work all right on my end: https://i.imgur.com/jBxLn5J.png
