From 90cd1bac4eeb0d57fbe2740625aaa58d8d925ee5 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Tue, 30 Oct 2012 22:32:37 +0200 Subject: lib: add date range query support Add a custom value range processor to enable date and time searches of the form date:since..until, where "since" and "until" are expressions understood by the previously added date/time parser, to restrict the results to messages within a particular time range (based on the Date: header). If "since" or "until" describes date/time at an accuracy of days or less, the values are rounded according to the accuracy, towards past for "since" and towards future for "until". For example, date:november..yesterday would match from the beginning of November until the end of yesterday. Expressions such as date:today..today means since the beginning of today until the end of today. Open-ended ranges are supported (since Xapian 1.2.1), i.e. you can specify date:..until or date:since.. to not limit the start or end date, respectively. CAVEATS: Xapian does not support spaces in range expressions. You can replace the spaces with '_', or (in most cases) '-', or (in some cases) leave the spaces out altogether. Entering date:expr without ".." (for example date:yesterday) will not work as you might expect. You can achieve the expected result by duplicating the expr both sides of ".." (for example date:yesterday..yesterday). Open-ended ranges won't work with pre-1.2.1 Xapian, but they don't produce an error either.
