Subject Re: question about function query
Date Fri, 17 Mar 2017 08:38:42 GMT
Hi Mikhail,

thanks for your help.
After some more reading and testing I found the solution.
Just in case someone else needs it here are the results.

original query:
q=collection:ftmuenster+AND+-description:*&fl=*
--> numFound="1877"

frange query:
q=collection:ftmuenster&fq={!frange+l=0+u=0}exists(description)
--> numFound="1877"

original query:
q=collection:ftmuenster+AND+description:*&fl=*
--> numFound="4152"

frange query:
q=collection:ftmuenster&fq={!frange+l=1+u=1}exists(description)
--> numFound="4152"


Regards
Bernd
