Question

I am a newbie of Solr using version 6.5.0. How can i change name of function query field like alias name in mysql. In below response hsin field showing data in a field name as "hsin(6371, true, latitude, longitude, 0, 0)" i want to change that field name into a "distance". How can i do that?

        "hsin(6371, true, latitude, longitude, 0, 0) ":7560.780673825484}]
  }}

Answer 1

The only thing that you need to change is the fl parameter, since Solr 4.0 (if I don't remember incorrectly) you can rename fields that you request using the fl parameter, so you just need something like:

fl=distance:hsin(6371, true, latitude, longitude, 0, 0)

This would return then the result of the calculation in the distance field.
