Problem with white space or special characters in function queries

[Shamik Bandopadhyay]

Hi,

   I'm having trouble handling white space or special characters in
function queries. Here's a sample function:

if(termfreq(ADSKFeature,'CUI (Command)'),log(CaseCount),sqrt(CaseCount))

I tried escaping the space with "\", but that didn't work either. Here's
the exception being thrown:

org.apache.solr.search.SyntaxError: Expected identifier at pos 0
str='(Command)'),log(CaseCount),sqrt(CaseCount))'

This happen with other special characters like &, ?, etc.

Does function queries have any limitations? Or am I doing something wrong?

Any pointers will be highly appreciated.

Thanks,
Shamik
