Subject [jira] Commented: (LUCENE-252) [PATCH] Problem with Sort logic on tokenized fields
Date Wed, 07 Mar 2007 19:15:24 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12478856

Doug Cutting commented on LUCENE-252:
-------------------------------------

I am not convinced that we should encourage folks to use a FieldCache with a tokenized field
in this way, expecting the untokenized, stored value.  It is considerably slower to populate
the cache this way, greatly reducing its utility.  Instead we should probably improve the
documentation on this point, and perhaps even throw an exception for tokenized fields.

> When you set s SortField to a Text field which gets tokenized
> FieldCacheImpl uses the term to do the sort, but then sorting is off 
> especially with more then one word in the field. I think it is much 
> more logical to sort by field's string value if the sort field is Tokenized and
> stored. This way you'll get the CORRECT sort order
