Thanks Shawn for providing more info. The looks like for supporting partial date range search, I would need to rely on String regex search like fieldName:2016-01*
Though this can support part of the functionality, but if I would like to search between start and end date, this might not come good, like fieldName:[2016-01-10 TO 2016-01-21]. This cannot be achieved by indexing the date in String field. Hence as you mentioned, I would need to upgrade my solr to 5.x to fully support this. Thanks again. -Sriram -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-partial-date-range-search-tp4253226p4253412.html Sent from the Solr - User mailing list archive at Nabble.com.
