Search function query

[Ron Piggott (PHP)]

I am writing a search function.  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 * FROM `store_product_profile` WHERE `product_name` LIKE '%
$search_string%' AND `product_description` LIKE '%$search_string%' AND
`keywords` LIKE '%$search_string%'

I have found the concept I am looking for on the mySQL web site:

SELECT MATCH('Content') AGAINST ('keyword1 keyword2') as Relevance FROM
table WHERE MATCH ('Content') AGAINST('+keyword1 +keyword2' IN BOOLEAN
MODE) HAVING Relevance > 0.2 ORDER BY Relevance DESC

I don't know how to apply this to the 3 fields in the data I want to
search with the users search string ( product_name ,
product_description , keywords )  The search string in the form is
"search_string"

Could someone show me how to make this work with what I have described
please?

Ron

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?  Ron

SELECT MATCH (
`product_name` , `product_description` , `keywords`
)
AGAINST (
'postcard'
) AS Relevance
FROM store_product_profile
WHERE MATCH (
`product_name` , `product_description` , `keywords`
)
AGAINST (
'postcard'
IN BOOLEAN
MODE
)
HAVING Relevance > 0.2
ORDER BY Relevance DESC

Have you tried removing the HAVING clause?

The '0' relevance is probably because 'postcard' is present in a lot  
of rows . Try adding more rows with different content and also try  
searching for different products. Your query looks fine to me.
