Re: Pattern: Is there a method of resolving multivalued date ranges into a single document?
Nobody? I don't have problem with the hours but I do have the same situation with dates where a document could be in many date ranges. Any suggestion?

I'm looking to implement something similar. Has anybody worked something out to work around this issue? Any guidance is greatly appreciated!

Re: Pattern: Is there a method of resolving multivalued date ranges into a single document?
Juidoo - there's no field wildcarding in Solr as your example shows. You might want to consider building a document for each movie time that includes all the information you need to search on: times, movie name, and other details. Otherwise you need a join operation to search across related documents, something you may be familiar with from relational databases that Solr is only just now getting some support for in new development. -Mike On 6/11/2011 5:02 PM, Judioo wrote: Hi All, Question on best methods again :) I have the following type of document. film titleTron/film times time start='2010-09-23T12:00:00Z' end='2010-09-23T1430:00:00Z' theater_id='445632'/ time start='2010-09-23T15:00:00Z' end='2010-09-23T1730:00:00Z' theater_id='445633'/ time start='2010-09-23T18:00:00Z' end='2010-09-23T2030:00:00Z' theater_id='445634'/ /times . /film where theater identifies the place where the film is showing. Each theater is stored in another document. I want to store the timings in the same document as the film details. This is so I can perform a range search like ( type:film AND start:[ NOW TO * ] AND end:[NOW TO *] ) i.e. give me all the films that are scheduled to start in the future. I was hoping I could submit a document like the following: doc field name=id12345-67890-12345/field field name=titleTron/field field name=445632_start2010-09-23T12:00:00Z/field field name=445632_end2010-09-23T1430:00:00Z/field field name=445633_start2010-09-23T15:00:00Z/field field name=445633_end2010-09-23T1730:00:00Z/field field name=445634_start2010-09-23T18:00:00Z/field field name=445634_end2010-09-23T2030:00:00Z/field /doc My assumption is that I could then perform a wildcard date range search like ( type:film AND *_start:[ NOW TO * ] AND *_end:[NOW TO *] ) Using the attribute name theater_id_start|end as an indicator to the theater. However I do not think date ranges support this. Can ANYONE suggest a method to accomplish this with examples? Thank you in advance.
Re: Pattern: Is there a method of resolving multivalued date ranges into a single document?
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.
