Subject [jira] Commented: (SOLR-1131) Allow a single field type to index multiple fields
Date Fri, 11 Dec 2009 15:46:18 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1131?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12789351#action_12789351

Grant Ingersoll commented on SOLR-1131:
---------------------------------------

bq. Unfortunately, it's at the cost of readability and maintainability. 

Maybe.  It took me all of 30 seconds to figure out what it was doing.  I'll put some comments
on it.  While readability is important, Solr's goal is not to make a product that a CS101
grad can read, it's too build a blazing fast search server.  That call could hit millions
of times when indexing points.

> In a few special cases, it makes sense for a single "field" (the concept) to be indexed
as a set of Fields (lucene Field).  Consider SOLR-773.  The concept "point" may be best indexed
in a variety of ways:
>  * geohash (sincle lucene field)
>  * lat field, lon field (two double fields)
>  * cartesian tiers (a series of fields with tokens to say if it exists within that region)
