perf(search): Resolved issue with SearchKit

[tom-ludwig]

Description

This PR addresses an issue where the search algorithm was unable to process certain special characters (e.g.,, (, *, :). This limitation prevented users from finding content that included these characters in their queries.

For example, searching for "info": in a JSON file would not return any results due to this limitation.

Contents.json:

{
    "info": "xcode": {
        [...] 
    }
}

The fix in this PR corrects the search algorithm to handle these special characters, allowing users to successfully search for content that includes them.

Finally ready for review. It was tougher to come up with those 21 lines than the original 400. Good thing I found a bug during testing, which I've fixed now. Could you guys test some queries on your projects to make sure everything's working right?

Might want to put some XCTests in place as well?
