Hoss Man updated SOLR-6540:
---------------------------
Description:
If you try to use the strdist function on a field which is missing in some
docs, you'll get a NullPointerException
A workarround in some contexts can be to wrap the strdist function in an "if"
that checks exists(fieldname) and returns some suitable default if it's not
found.
{code}
THIS: if(exists(field_name_s),strdist("literal",field_name_s,edit),0)
INSTEAD OF: strdist("literal",field_name_s,edit)
{code}
