Subject: [PHP] search results return by relevancy
Hi there
I have some scripts that do a search in a MySQL database
table.
I want to be able to return rows that match a query, in
order of relevancy.
For example, say I have a table that has the following data
|row_id| data
|------|-------------------------------------
| 1 | cat
| 2 | cat cat
| 3 | cat cat cat
| 4 | cat cat
| 5 | cat cat cat cat cat cat cat
| 6 | cat
| 7 | cat cat cat cat
| 8 | cat cat cat cat cat
I want to do a search that would return row_id 5 first, then
row_id 8, then row_id 7, then 3, etc.
So I want to order the return by relevancy.
What should the sql query look like?
select * from table where data like '%cat%' order by ?????
thanks
-jen
