Query\Builder::whereRaw() doesn't accept parameters

[guoyunhe]

I have the following code and expect to pass $search into the raw query:

$tags = Tag::whereHas('translations', function ($query) use ($search) {
    $query->whereRaw("MATCH(`name`) AGAINST(? IN BOOLEAN MODE)", [$search]);
    echo $query->toSql();
})->get();

SQL dump:

select * from `tag_translation` where `tag_translation`.`tag_id` = `tag`.`id` and MATCH(`name`) AGAINST(? IN BOOLEAN MODE)

The ? is not replaced by $search.

Cannot find useful document about the whereRaw() function. Is here any good way to excute a raw SQL for fulltext index?

Found my problem. The query won't fill ? with bindings until it is executed.
