Subject [jira] [Updated] (SOLR-2345) Extend geodist() and geofilt to support MultiValued lat long field
Date Sun, 22 May 2011 00:11:47 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2345?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bill Bell updated SOLR-2345:
----------------------------

    Description: 
Extend geodist() and {!geofilt} to support a multiValued lat,long field without using geohash.

sort=geodist() asc



  was:
Extend geodist() and potentially other functions to support MultiValue fields for sorting
and scoring.

sort=geodist() asc

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.

sources:[double(store_0_coordinate), double(store_1_coordinate)]

How do I extend the sources?

        Summary: Extend geodist() and geofilt to support MultiValued lat long field  (was:
Extend geodist() to support MultiValuefield for sorting/scoring)
