Judioo, This is an interesting problem I've contemplated before. I've been working on geospatial support for Solr using a prefix/tree/grid technique that supports multi-valued fields. Geo/spatial might be 2D (x,y), but your problem is 1D (time) which means you can use spatial techniques just by ignoring one dimension. There is a "geohash" field type as of Solr 3.1 supporting multi-valued fields but its implementation leaves much to be desired. It might work for you, and it would certainly be a hack, but it might be too Geo oriented, forcing you to map your times to a -180 TO +180 range. I hope to add better support for this problem to Solr by the end of the year.
Good luck. ~ David Smiley ----- Author: https://www.packtpub.com/solr-1-4-enterprise-search-server/book -- View this message in context: http://lucene.472066.n3.nabble.com/Pattern-Is-there-a-method-of-resolving-multivalued-date-ranges-into-a-single-document-tp3053882p3054714.html Sent from the Solr - User mailing list archive at Nabble.com.
