Today I want to work out the data anomaly I have for dewiki. It looks like the number of newcomer created drafts falls off abruptly in the middle of 2011. So, I'd like to find some move events from the middle of that period (let's say, 2011/09-2011/10) to see what the revision comments look like and figure out if my regex was matching them properly or not.

OK. Time to look for the page.

OK. Now to check if my regex matches.

It doesn't match. So now to figure out how to make the regex match. It should be pretty easy.
> select rev_comment RLIKE ".*(hat „|verschob „|verschob die Seite )\\[\\[([^\]]+)\\]\\]“? nach „?\\[\\[([^\]]+)\\]\\]“?(.*)" from revision where rev_page = 55428 and rev_user = 995197; +--------------------------------------------------------------------------------------------------------------------------------+ | rev_comment RLIKE ".*(hat „|verschob „|verschob die Seite )\\[\\[([^\]]+)\\]\\]“? nach „?\\[\\[([^\]]+)\\]\\]“?(.*)" | +--------------------------------------------------------------------------------------------------------------------------------+ | 1 | +--------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.03 sec)
There we go. Time to kick off the move detector again. With any luck, I can have new data by the end of the day. --Halfak (WMF) (talk) 17:52, 21 January 2014 (UTC)
