match-against

When I execute this query with MATCH AGAINST using MySql ( see Query 1st ) the issue in this query they has generated an error like this ( see error ) or when I execute the same query with = they executed normally( see Query 2nd ). My question is what am I doing wrong with against statement? Query 1st SELECT (SELECT COUNT(up.`user_id`) FROM `users_post` up WHERE MATCH (up.`user_id`) AGAINST (uf.`user_id`)) AS user_count FROM `users` uf Error enter code hereError Code : 1210 Incorrect arguments to AGAINST (0 ms taken) Update Query 2nd SELECT (SELECT COUNT(up.`user_id`) FROM `users_post` up

I have a problem with the MATCH AGAINST function. The following query give me the same result: SELECT * FROM models MATCH(name) AGAINST('Fiat 500') SELECT * FROM models MATCH(name) AGAINST('Fiat') How can I search for both strings and numbers in a column of a FULL TEXT table? Thanks If you need Fiat and 500 anywhere where order does not matter, then SELECT * FROM models MATCH(name) AGAINST('+Fiat +500'); If you need Fiat 500 together, then SELECT * FROM models MATCH(name) AGAINST('+"Fiat 500"'); If you need Fiat and zero or more 500 , then SELECT * FROM models MATCH(name) AGAINST('+Fiat 500');
