[Wikia-l] Why does full-text search for "CSV" fail?

[John Beckett]

Some users have reported that searching for "CSV" does not work on our wiki.
Strangely, searching for "comma" does work (CSV = comma-separated values). As a
workaround, I have made a redirect page with title "CSV", so a default search will
now find our CSV page.

However, why does a full-text search for "CSV" fail (it works on Wikipedia)?

One way to test this is to enter "CSV" or "csv" (without quotes) in "Search the
tips" on our main page, then click "Search full text":
