Subject [jira] [Commented] (SOLR-2345) Extend geodist() to support MultiValuefield for sorting/scoring
Date Sun, 22 May 2011 00:09:47 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13037482#comment-13037482
] 

Bill Bell commented on SOLR-2345:
---------------------------------

If we can change geodist() and {!geofilt} to work on lat_long multiValues. This would allow
more flexibility. So a person with multiple addresses will be supported.

I worked on geomultidist() in SOLR-2155. We would just need to support this in the actual
filter to limit the results for the multi value list.

Thoughts?

Thanks.

> This should grab the closest point in the MultiValue list, and return the distance so
that is can be scored.
> The problem is I cannot find a way to get the MultiValue list?
> In function: src/java/org/apache/solr/search/function/distance/HaversineConstFunction.java
> VectorValueSource p2;
> this.p2 = vs
> List<ValueSource> sources = p2.getSources();
> ValueSource latSource = sources.get(0);                 
> ValueSource lonSource = sources.get(1);                 
> DocValues latVals = latSource.getValues(context1, readerContext1);
> DocValues lonVals = lonSource.getValues(context1, readerContext1);
> double latRad = latVals.doubleVal(doc) * DistanceUtils.DEGREES_TO_RADIANS;
> double lonRad = lonVals.doubleVal(doc) * DistanceUtils.DEGREES_TO_RADIANS;
> etc...
> It would be good if I could loop through sources.get() but it only returns 2 sources
even when there are 2 pairs of lat/long.

> How do I extend the sources?
