Improve Icon Search

[mdSlash]

Searching for icons can be challenging when you're limited to searching by name alone. Many times, I forget the exact name of a specific icon and need to find it using related keywords. Adding categories or aliases to the index.csv file would make it easier to find the right icon, improving the search process and making it more efficient. Additionally, fuzzy finding doesn’t always address this issue effectively, so incorporating categories or aliases is essential for a more reliable search.
