SIMPLE ONE HOUR PROJECT: Need PHP script modification

This is a very simple project and the pay is $40. Currently this script is to search for songs in our music database. How it works: The user starts typing the first letter or two of a title OR artist, and what is in the library starts populating below. in a selectable list. The user then selects from the list then submits, and the song will be played instantly on our app. The problem is that when a user types contractions with apostrophes, the songs dont come up (songs with words like don't, can't, ke$ha, or other characters). the second problem is that songs that have multiple artists attached to them dont populate in the list. 1)Songs MUST be able to be found if a user types dont OR don't, also if an artist has a special character in their name like Ty Dollar $ign, the user should be able to type it either $ign, or sign and it wil still be found 2)Songs with collaborations like marshmello ft justin bieber or calvin harris / ariana grande, etc MUST be found when the user types in ANY artist that is in the file tags. Currently it only searches for the FIRST artist listed, and not the second, third or fourth listed in the mp3 tag. This project you will just change how our existing script searches our music library so that it finds songs indicated above. ALL SOURCE FILES YOU NEED ARE ATTACHED. Final deliverables will be sent and uploaded for us to test. You must test this without having access to any of our servers, or credentials. If you cannot do this without access, then please dont bid. Looking to complete this project within 12 hours of it being assigned. All funds awarded, upon deliverables of all source code.
