Is your feature request related to a problem? Please describe.
Searching for a "Bard" or an "Half-orc" isn't currently possible in the directory, you can only search by name

Describe the solution you'd like
We would like to add an advanced search bar allowing for tag search through specific syntax, like class:bard or race("orc") or else. The tool could be designed in a way allowing it to be reused for multiple other purposes (https://github.com/Ellypse/Total-RP-3-Extended/issues/20 or https://github.com/Ellypse/Total-RP-3/issues/35 for instance), supporting a variety of keywords like and, or, a wildcard character or quotation marks for exact match, or whatever else comes to mind at the time...
