From two years ago to earlier this week, "?DEEGNO" (or ADEEGNO) with "A" entered into "MATCH THIS" with neither box checked would return all words containing "A" -- not just those with the A at the beginning or the end (provided the appropriate box was checked).

Since a few days ago, however, "MATCH THIS" doesn't work at all unless a box is checked.

...which basically guts at minimum half if the reason I used thus site.
