improved search function

Customer is a vape shop with a lot of items with similar names. They are requesting improvements to the search function in the pos. 
if they start a search for an item that is multiple words they have to get the words in the correct order for it to find it, if they miss a word in the middle it won't find it.
eg "Kratom Vape Raspberry" will find it, "Kratom Raspberry" will not find it.
