Subject Re: Solr data type for date faceting
Date Wed, 18 Aug 2010 08:37:08 GMT
If you're storing the timestamp as YYYYMMDDHHMM, why don't you make it  
a trie-coded integer field (type 'tint') rather than text?  That way,  
I believe range queries would be more efficient.  You can then do a  
facet query, specifying your desired ranges as one facet query for  
each range.

Note that I think you can also do facet queries with text fields, but  
in this instance, storing it as a number would probably be more  
efficient.  Your user interface can deal with translating it from  
YYYYMMDDHHMM to something more display-appropriate.
