AbstractLuceneSpellChecker is expecting a string, but getting a float.
Can you paste here the config (in solrconfig.xml) for your spellchecker?
Also, a simple way to get spell checking started is to look at the
/browse example that comes with the techproducts sample configs. It has
spellchecking already working, so starting there can be a way to get
something going easily.

The nc output lets us see everything that your client sent to Solr, so
I
have built a test URL for you based on that info.
Try sending the following URL from a browser or a curl command. If
I've
gotten the host wrong, go ahead and replace it with the correct value.
You'll probably be able to see any errors right in the browser or curl
output. Hopefully this will help you figure out what's happening.
Also
look in your Solr server's logfile for error messages.
http://dell9-tir:8983/solr/EventLog/spellCheckCompRH?qt=%2FspellCheckCompRH&q=Some+more+text+wit+some+missspelled+wordz.&spellcheck=on&spellcheck.build=true&wt=json&indent=true
I notice that you have "spellcheck.build=true" in that URL. You
probably don't want to do this on every request, assuming that your
spellcheck dictionary even requires building.
Thanks,
Shawn
It wasn't really a problem request, but a follow-up to those who took
the time to help me. However, since this error has returned, it is now
a problem request! ;-)
I am aware that "spellcheck.build=true" is expensive, but since I
haven't had my first success yet with spell-checking, I figured it
wouldn't hurt to have it in there for now.
I ran the URL you gave verbatim (because your assumptions were correct),
but I got the stacktrace shown below. This is particularly puzzling
because I can find nowhere in my code or configuration where I am
specifying a float value where I shouldn't be. My solrconfig.xml and
schema.xml are posted in another thread having a subject "Moving on to
spelling" if that helps you help me.
Thanks,
Mark
