Even i have a similar requirement. I need the percentage match. The way I am going about it is doing 2 searches
eg if my search string is "pizza cheese " and my document has " pizza cheese ketchup" percentage match = ( score of searching "pizza cheese" in " pizza cheese ketchup") / ( score of searching "pizza cheese" in "pizza cheese") If there is a better way of going about this , please do let me know .
