+Additionally, I'd suggest to support value range queries for dates with\r
+".." syntax. Besides that some users may relay on this syntax, I use\r
+date searches a lot and with custom query parser I have to type\r
+"after:yesterday", which is unnecessarily long. I wish that\r
+"yesterday..", which is much easier to type, would do the same.\r
+Similarly, "mon..wed" would be easier to type than "after:mon\r
+before:wed". What do you think?\r
