Hi Peter :-),
did you already try other values for
hl.maxAnalyzedChars=2147483647
? Also regular expression highlighting is more expensive, I think.
What does the 'fuzzy' variable mean? If you use this to query via
"~someTerm" instead "someTerm"
then you should try the trunk of solr which is a lot faster for fuzzy or
other wildcard search.
Regards,
Peter.
