Solr field searching, wildcards, and escaped characters

I'm using solr for the search functionality on my webapp. I append an "*" to the end of each user's search. So, if the search is: foo I change it to filename:foo*

This works fine, except that often a hyphen will be included in the user's search. A search of filename:foo-bar* returns zero results, as the hyphen removes any search results produced from the search term(s) after it. I can escape it, as filename:foo\-bar* but I still get zero results. If I try filename:foo"-"* the search returns all documents.

Any suggestions on how to get - and * to play nice with one another?

Thanks for the help

In my experience, I've had to escape the wildcard character if anything else in the string is escaped. This is to get it to function as a wildcard; you'd think it'd make it look for the character itself, but it seems not to. Note: Escaping the * without other escaped characters seems to search exactly for the character *, and does not use it as a wildcard operator.

field:*and\/or* //would NOT perform a wildcarded search for "and/or"

field:\*and\/or\* //would perform wildcard search for and/or

To be clear, it seems like they are backwards, but that is what hass worked in my cases.
