[jira] [Created] (SOLR-12273) Create Stream Evaluators for distance measures

Joel Bernstein created SOLR-12273:
-------------------------------------

             Summary: Create Stream Evaluators for distance measures
                 Key: SOLR-12273
                 URL: https://issues.apache.org/jira/browse/SOLR-12273
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Joel Bernstein


Currently distance measures are instantiated by passing the name of the distance measure to a function, for example the *knn* function can be passed the named parameter: distance="manhattan". 

This ticket will create a specific function for each distance measure which will be used to specify which distance measure to apply. With this design the *knn* function would be passed the function: manhattan() or any of the other distance measure functions.
