Hi, I am getting the following error when using the hsin function: org.apache.lucene.queryParser.ParseException: Cannot parse '(: AND val:"recip(hsin(12.9365,77.5447,lat,long,3963.205,true), 1, 1, 0)")': Unknown function hsin in FunctionQuery('recip(hsin(12.9365,77.5447,lat,long,3963.205,true), 1, 1, 0)', pos=11)
Has anyone faced this issue? Any ideas how I can solve this? I am using solr version 1.4 and have not tried upgrading yet.
Thanks, Sapna
