Re: Sorting dates with reduced precision
AFAIK, according to the manual you can add multiple sort instructions: http://wiki.apache.org/solr/CommonQueryParameters#head-9f40612b42721ed9e1979a4a80d68f4f8524e9b4 - Markus Jelsma Buyways B.V.

Re: Sorting dates with reduced precision
Perhaps i don't see your problem but if you convert the dates to UNIX timestamps, you could use a range query to narrow your results to within a specific date. - Markus Jelsma Buyways B.V.

Re: Sorting dates with reduced precision
my bad, there are indeed some very nice features concerning datefields and processing although they aren't really thorougly documented in the wiki. http://wiki.apache.org/solr/IndexingDates http://lucene.apache.org/solr/api/org/apache/solr/util/DateMathParser.html some additional information for dates within facets can be found in http://wiki.apache.org/solr/SimpleFacetParameters#head-068dc96b0dac1cfc7264fe85528d7df5bf391acd - Markus Jelsma Buyways B.V.

What if I want to say "Sort so that withing entries for Nov. 2 , you sort by relevance" for example? Append "/DAY" to the date value you index, for example "1995-12-31T23:59:59Z/DAY" will yield "1995-12-31" So that all documents with the same date will then be sorted by relevance or whatever you specify as the next criteria in the "sort" parameter. Thanks, this happens at indexing time? kind regards, Tarjei
