mysql关键字搜索全文

Question

I am looking for a keyword search on my website and having a bit of difficulties

$q = "SELECT * from post WHERE post_k like '%".$_GET['s']."%'";

website url after search is website.com/?s=keyword

I am not getting fulltext searches. For example if I search for robin I can get results from batman because they both have n in the word. I am looking for a search that if I type robin I will only get results from robin.

Thanks

You need to use MATCH AGAINST with FULLTEXT INDEX .

CREATE FULLTEXT INDEX search_index ON post (post_k); 

Then your query would be more like (Example using prepared statements with MySQLi):

$query = $mysqli->prepare("SELECT * FROM post WHERE MATCH(post_k) AGAINST(?)");
$query->bind_param('s', $_GET['s']);
