MySQL sort by number of occurrences

Question

I am doing a search in two text fields called Subject and Text for a specific keyword. To do this I use the LIKE statement. I have encount

Answer 1

You want SUM instead. Count will count how many records have non-null values, which means ALL matches and NON-matches will be counted.

SELECT *, SUM(Text LIKE '%Keyword') AS total_matches
...
ORDER BY total_matches

SUM() will count up how many boolean true results the LIKE produces, which will be typecast to integers, so you get a result like 1+1+1+0+1 = 4, instead of the 5 non-nulls count.
