: The query would actually look like : fq=effDate_tdt:[2011-05-01T00:00:00Z TO 2011-05-31T00:00:00Z]
i think your overlooking part of the question ... Don seems to be asking how to query if the value of a date field contains a day in the month of may, regarldess of year... : >>the query would only return these : >> : >><date name="*effDate_tdt*">2011-05-017T00:00:00Z</date> : >><date name="*effDate_tdt*">2006-05-30T00:00:00Z</date> : >><date name="*effDate_tdt*">2004-05-03T00:00:00Z</date> ...this isn't possible with the solr date field. you'll need to create a special "month" field and index just the month value there. -Hoss
