Greetings,
Using an Index-based spell-checker, I get some results, but not what I'm
looking for. Using a File-based checker, I never get any results, but
no errors either. I've trimmed down my configuration to only use one
spell-checker and named it "default", but still empty results on my text
that is chock full of misspelled words. Any ideas? Attached is my
solrconfig snippet:
