I am trying to create a lucene expression for displaying division on counts of two queries. Both queries contain textual information and both results are in message field. I am not sure how to write this correctly. So far what i have done is without any luck -
doc['message'].value/doc['message'].value
for first query message
contain text as - "404 not found"
for second query message
contain text as - "500 error"
what i want to do is count(404 not found)/count(500 error)
I would appreciate any help.
