Subject [jira] Commented: (SOLR-1131) Allow a single field type to index multiple fields
Date Tue, 15 Dec 2009 12:09:18 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1131?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12790715#action_12790715
] 

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

bq. It is not clear as to why can't the 'sf' instance be cached and reused? 

Because there is no way to change the name on a SchemaField w/o changing SchemaField to be
non-final.  I don't think SchemaField should be non-final.

bq. Why do we have a map for flags why not use a bitset?

Yeah, we could add a new method that takes a bitset, b/c I believe that is what is used under
the hood anyway.

> 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)
