Grant Ingersoll updated SOLR-1302: ---------------------------------- Attachment: SOLR-1302.patch Haversine implementation, RadianFunction and DegreeFunction. Also small refactorings in other places to better support doubles to avoid losing precision for as long as possible. Next up: Euclidean and SquaredEuclidean > Fun with Distances - Add Distance functions for a variety of things > ------------------------------------------------------------------- > > Key: SOLR-1302 > URL: https://issues.apache.org/jira/browse/SOLR-1302 > Project: Solr > Issue Type: New Feature > Reporter: Grant Ingersoll > Assignee: Grant Ingersoll > Priority: Minor > Fix For: 1.5 > > Attachments: SOLR-1302.patch > > > There are many distance functions that are useful to have: > 1. Great Circle (lat/lon) and other geo distances > 2. Euclidean (Vector) > 3. Manhattan (Vector) > 4. Cosine (Vector) > For the vector ones, the idea is that the fields on a document can be used to > determine the vector. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
