Mysql search fields different order

Question

I have a table like this

name  | surname   | email         | tel
Edwin | Williams  | edwin@aa.com  | 123456
Luke  | Evan      | luke@bb.com   | 987456

I need to search "Edwin Williams" or "Williams Edwin" as the same.

I tried

CONCAT_WS (' ', name, surname, email, email2) LIKE '%".addslashes($_POST['search'])."%'
OR
CONCAT_WS (' ', surname, name, email, email2) LIKE '%".addslashes($_POST['search'])."%'

but I don't like it, in I search "123456 Edwin" I don't find anything.

I have table in InnoDb, I prefer not use MyISAM fulltext.

Answer 1

I think you want:

WHERE CONCAT_WS(' ', name, surname, email, email2, tel) REGEXP REPLACE(CONCAT('%', $_POST['search'], '%'), ' ', '|')

You want a vertical bar to get "OR" for a regular expression.
