Subject [jira] [Commented] (SOLR-2533) Improve API of ValueSource & FunctionQuery SortField weighting
Date Sun, 22 May 2011 00:57:47 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13037488#comment-13037488
] 

Yonik Seeley commented on SOLR-2533:
------------------------------------

The query.rewrite model isn't strongly typed and seems to work fine.  The advantaged is that
99% of the time the SortField will remain unchanged (and the base-class implementation of
"return this" will be used).  That's much less of an API change too (rather than moving a
whole bunch of Sort methods to WeightedSort).

> Started from LUCENE-2883: Support for sorting by ValueSource and FunctionQueries is done
through ValueSource#getSort and the ValueSourceSortField.  In order to support VSs containing
other Queries, its necessary to allow the Querys to be weighted by an IndexSearcher.  Currently
this is handled by having ValueSourceSortField implement SolrSortField.  In Solr's SolrIndexSearcher,
SortFields implementing SolrSortField are then weighted before the Sort is used.
> Sorting by FunctionQuery and ValueSource are invaluable and will become available to
all Lucene users in LUCENE-2883.  But in order to do so, we need to remove the coupling of
this functionality to Solr, and make it more standard.
> Any and all thoughts about how to do this are appreciated.
