"Browse" doesn't search anything - it just displays all of the tracks on your device in the order that you set as default, or chosen to sort them.
If you're looking to search, that will look at a variety of fields, including the song title, artist, album, and comment.
All of this relies on you having exported the content from rekordbox to your USB device. Any files not prepared in this manner won't be available through the browsing options, only the FOLDER method. As such, the file type doesn't matter - the database created on your export drive from rekordbox will be what the unit is pulling the data from.


Then double-click it to open it, and the action editor will open. Click Fields then double click File to Tag and it will add an action to the right pane:

You're now at the File to Tag preferences window, click the + icon at the bottom, then give your new template a name:
Click Add Token and insert the fields you want it to grab from the filename, so if your WAV filename is formatted ARTIST - SONG NAME (REMIX).wav, you would possibly only add the Artist tag, then press space, then hyphen, then space again, then the Title tag, as REMIXER is an available tag, but not for a WAV file.
