Subject [jira] Commented: (SOLR-1298) FunctionQuery results as pseudo-fields
Date Tue, 21 Jul 2009 14:17:14 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12733631#action_12733631

Chris Male commented on SOLR-1298:
----------------------------------

In my patch in SOLR-773, I tackled this issue by creating the idea of a FieldValueSource,
which mapped a name of a pseudo-field to an arbitrary source of data which could be computed
at runtime.  For me it was distances, but it could also be the results of a FunctionQuery.
 Since there was a mapping of name to data, it was possible to include or exclude the FieldValueSources
from adding their information to the search results through the fl parameter.

> It would be helpful if the results of FunctionQueries could be added as fields to a document.

> Couple of options here:
> 1. Run FunctionQuery as part of relevance score and add that piece to the document
> 2. Run the function (not really a query) during Document/Field retrieval
