+Please find in the previous mail attached my patch (against my current\r
+all-feature branch, but should pretty much apply to current master too).\r
+It is a proof-of-concept to make the date parser nicer. The following \r
+searches work with this code:\r
+\r
+notmuch show...\r
+... date:2001..2010 (from beginning of 2001 until end of 2010)\r
+... date:20011201..200506 (from 1001-12-01 until 2005-06-31\r
+\r
+The code will pretty surely need some cleaning up, as I can hardly code\r
+C, not to speak of C++. But at least it works and it is not very\r
+intrusive.\r
+\r
+(Ps. now that I think of it, I always use day 31 as last day, which is\r
+surely wrong, it also still accepts some obviously wrong dates like\r
+20040231)\r
+\r
+We could also think about using a xapian DateValueRangeParser to do\r
+that, but that would require saving the timestamp as YYYYMMDD in the\r
+database (which we probably do not want).\r
+\r
+Feedback welcome,\r
+Sebastian\r
