Have you tried removing the HAVING clause?

I just made a FULLTEXT index on the 3 fields I want to search (product_name, product_description and keywords) and then created the mySQL query below with a search for the word "postcards". It didn't have any results though. I don't understand why because the word 'postcard' exists in the product_name field a few times. Any idea what I have done wrong / or why this is happening?

Is there a way to enhance this query so it will display the best matches first down to the least matches? As well I don't know how to handle if the user types in more than 1 word to search. SELECT * FROMstore_product_profileWHEREproduct_nameLIKE '% $search_string%' ANDproduct_descriptionLIKE '%$search_string%' ANDkeywordsLIKE '%$search_string%' Ron
