Shawn, Thank you for that. I didn't know about that feature of the WDF. It doesn't help my situation but it's great to know about. Googling solr wildcard searches I found this link http://lucene.472066.n3.nabble.com/Wildcard-search-not-working-with-search-term-having-special-characters-and-digits-td4133385.html
"The use of a wildcard in a query term with embedded special characters will bypass normal analysis - you need to enter the term exactly as it would be analyzed at index time for wildcard to work." To me this seems like a design flaw. The Solr fieldtypes seem like they allow a developer to create types that should handle wildcards intelligently. At the very least the Analyzer tool should show this behavior, and not even try to analyze terms with wildcards. Actually the behavior would more correctly be stated as "You need to enter the term exactly as the data is after it has been indexed" If the fieldtype removes hyphens then you must enter the wildcard query without hyphens.
