How do I modify the SQL syntax to have the same word count as 1 in the post?

"As shown in the code below, the total of multiple strings such as ""delicious"" and ""delicious"" in the body column of the DB table can be displayed on the Blade, but if there are multiple words such as ""delicious"" and ""delicious"" in one post, it will be counted as multiple."
I apologize for the inconvenience, but I would appreciate it if you could tell me how to correct it.Thank you for your cooperation.

controller:

$posts=DB::table('Post') ->select(db::raw("body,
(LENGTH(body)-LENGTH(REPLACE(body, 'delicious', ')))/LENGTH('delicious')AS cntA,
(LENGTH(body)-LENGTH(REPLACE(body, 'bad', ')))/LENGTH('bad')AS cntB,
")->distinct()->where('user_id', $user)->get();

Blade:

<p>"Delicious" was {{$posts->sum('cntA')}} times in total.</p>
<p> "bad" was {{$posts->sum('cntB')}} times in total.</p>
