I'm trying to figure out how to do date comparisons based on Acquisition date. The best information that I have is here: http://manual.koha-community.org/3.18/en/searchguide.html#searchguide-syntax Using the following pattern found in the documentation: su=supreme court and yr,st-numeric=>2000 I constructed the following search, which should have returned results: cgi-bin/koha/opac-search.pl?idx=acqdate,st-date-normalized&q=>2015-08-01 I have bibs indexed that have acquisition dates greater than 2015-08-01, but this returned the followng: Results of search for 'acqdate,st-date-normalized: >2015-08-01' No results found! I believe that date comparisons should be possible using CCL, according to what I've been able to glean from indexdata I must be missing somthing here... Thanks, --Barton
