Another thing to remember about wildcard and fuzzy searches is that none 
of the token filters will be applied.

If you are using the LowerCaseFilterFactory at index time, then 
"RI-MC50034-1" gets converted to "ri-mc50034-1" which is never going to 
match "RI-MC5000*"

Also, I would probably use the analyze page of your solr admin site to 
see what tokens are produced from "RI-MC500034-1" and "500034" based on 
your schema

I guess one thing you need to do is to add preserveOriginal="true" in the
WordDelimiterFactory section in your field type. That would help match
things like "RI-MC5000*". Make sure you re-index all documents after this
change.

As for the others, add debugQuery=on as a request parameter and see how the
query is being parsed. If you have a doubt, paste it on the list and we can
help you.
