: I'm trying to break down the data over a year into facets by month; to avoid : overlap, I'm using -1MILLI on the start and end dates and using a gap of : +1MONTH. : : However, it seems like February completely breaks my monthly cycles, leading
Yep. Everything you posted makes sense to me in how DateMath works - "Jan 31 @ 23:59.999" + "1 MONTH" results in "Feb 28 @ 23:59.999" ... at which point adding "1 MONTH" to that results in "Mar 28 @ ..." because there is no context of what the initial starting point was. It's not a situation i've ever personally run into ... one workarround would be to use a "+1MILLI" fudge factor at indexing time, instead of a "-1MILLI" fudge factor at query time ... that shouldn't have this problem. If you'd like to open a bug to trak this, I think it might be possible to fix this behavior (there are some features in the Java calendaring code that make things like "Jan 31 + 2 Months" do the right thing) but personally I think working on SOLR-1896 (combined with the new facet.range.include param) is a more effective use of time so we can eliminate the need for this type of hack completely in future Solr releases. -Hoss -- http://lucenerevolution.org/ ...
