mysql-在逗号分隔的文本字段中找到匹配项

Question

I am having problems with output from my (MySQL) database.

attractionData database

 id |  tags
-------------------------------------

 1  |  castle a, castle b, fakecastle c
 2  |  museum a, fakemuseum b, museum c
 ...

And on a site I have an input field, which has autoSuggest function. So in my jQuery I have an .keyup event, which send data to ajax file, and the ajax file outputs the list of suggestions (autosuggest).

So now if I type in the input "castle a..." it will output the "1" (im outputting the id). And if i type in "museum a" it will return "2".

So my question is... Is it somehow possible that if I would type in "fakecastle" that it would return "1"? I know this could be done with the explode(',', $string) .

I've been messing around with FIND_IN_SET(), but I somehow didn't achieve the result I wanted. So I am still stucked with

mysql_query("SELECT tags FROM attractionData WHERE (tags LIKE '$search%') ") $search = text from the input field.

EDIT

if(isset($_POST['search']) == true && empty($_POST['search']) == false){
    $search = $_POST['search'];
    $search = mysql_real_escape_string($search);

    $query = mysql_query("SELECT tags FROM attractionData WHERE (tags LIKE '$search%') ")
    while(($row = mysql_fetch_assoc($query)) !== false){
        echo "<li class='auto'>".$row['friendEmail'] ."</li>";
}

Any help would be appreciated

Ty, Sebastian
