+Hi everyone,\r
+\r
+I've been using notmuch for about a year now (using mutt-kz) and I am\r
+very happy with it. I have, however, a small suggestion about the range\r
+syntax in search queries. Often, I am looking for emails that have\r
+occurred, say, in the last week. The query has the following form:\r
+\r
+ date:today-1week..today\r
+\r
+The following syntactic sugar could shorten this kind of queries:\r
+ \r
+ date:r -> date:r..today, if r is a relative date\r
+ date:a -> date:a..a, if a is an absolute date\r
+ date:a-r -> date:a-r..a, for combination.\r
+\r
+(If r is interpreted as today-r, the first two transformations are\r
+subsumed by the last.)\r
+\r
+For example:\r
+ date:today -> date:today..today\r
+ date:-1week -> date:-1week..today\r
+ date:24.12.2014-4w -> date:24.12.2014-4w..24.12.2014 \r
+\r
+What do you think about this suggestion? Is this something notmuch would\r
+do, or rather something for xapian?\r
+\r
+With kind regards, Robert Künnemann\r
