+\r
+By seeing the thoughts thrown in IRC there seems to be plenty if things\r
+to resolve until something like this is going to be available in stock\r
+notmuch. In the meanwhile I provide some ideas into the soup; maybe\r
+our collective mind can have some use of this.\r
+\r
+\r
+Q: Could 'date:timestr' be converted to 'date:timestr..timestr' ?\r
+\r
+In this idea -<timestr> means relative time and <timestr> absolute\r
+time. The the time string consists of number and letter and assume\r
+the above suggestion for date:timestr (<- == date:timestr..timestr)\r
+Letters are s seconds h hours d days w weeks m months (more\r
+useful than for minutes) and y years.\r
+\r
+date:-2000s email exactly 2000 seconds ago (not very useful)\r
+date:-2000s.. since 2000 secs in past\r
+date:..-2000s up to 2000 secs in past\r
+\r
+date:3600s email with date 01:00 -- today if (local) time is\r
+ more than 1am. yesterday if less. If there is not\r
+ mail with date exactly that then no email matches\r
+ (i.e. same usefullness applies as above)\r
+date:3600s.. email with date since 01:00 (same today/yesterday\r
+ resolvation like above)\r
+\r
+date:12h.. since noon, either yesterday (time less than 12pm)\r
+ or today (currently afternoon)\r
+date:12h like above, but since 12:00 to 13:00\r
+date:12h..12h ditto\r
+\r
+date:6pm.. since 18:00 either today (current time > 6pm) or yesterday\r
+\r
+date:-12h.. since 12 hours ago\r
+date:-12h since 12 hours ago to 11 hours ago\r
+\r
+date:-1h last hour\r
+date:0h today 12am - 01am \r
+\r
+date:-0d today\r
+date:-0d.. ditto\r
+date:-1d yesterday\r
+date:-1d.. yesterday & today\r
+\r
+date:-2d 2 days ago\r
+date:-2d.. day before yesterday, yesterday & today\r
+\r
+date:0d last sunday (if today sunday, today (so being consistent))\r
+date:1d last monday (like above)\r
+date:6d last saturday (like above)\r
+date:7d last sunday (same as 0d)\r
+\r
+date:-0w current week (does week start sun or mon)\r
+date:-1w last week (same as above)\r
+date:-2w.. since beginning of 2 weeks ago\r
+\r
+date:1w (ISO) week number ? current week it this is same week \r
+ number. this week last year if current week is less.\r
+date:1w.. since the above date resolved.\r
+\r
+date:11m last november (m is more useable in month than in minute)\r
+date:11m.. since last november\r
+\r
+date:-11m whole month 11 months ago\r
+date:-11m.. since beginning of 11 months ago\r
+\r
+date:70y year 1970\r
+date:69y year 2069\r
+date:0y year 2000\r
+date:99y.. since beginning of 1999\r
+\r
+date:-0y this year\r
+date:-1y last year\r
+\r
+\r
+This is incomplete, but pretty easy to use format. Letters from English\r
+language. What is missing letter for month (M?) ar mday (D?). All thought\r
+as in local time...\r
+\r
+... strings could be concatenated: for example: -3d11h (meaning second\r
+always absolute). Need to be in granularity order (or something). Timezone\r
+could be added (pst, utc, eest, z -- and even like -11 or +4\r
+( -2y11m+7 meaning year 2010 november in timezone utc + 7 (this year: 2012))\r
+\r
+Of course range date:-2d..-5h would be supported.\r
