Back in 2004, I developed I wiki where the text was always split into words and the words were saved on the database. Then a post was just a list of word indexes.

It saved a TON of memory because most texts are just lots of duplicated words.

If you have that option, then you could quickly re-compute muted events by splitting the mute word into many, finding posts that each word appears in sequence and setting the mute flag.
