you can delete documents matching query indexwriter.deletedocuments method, such as:

string datestring = datetools.datetostring(mycutoffdate, datetools.resolution.day); query datequery = termrangequery.newstringrange("datefield", null, datestring, false, false); myindexwriter.deletedocuments(datequery);
