Really look at the analysis page in solr admin for how your analyzer chain handles things, or you'll spend time until you're really old having trouble :).
Here's what I see on a quick scan: > StandardTokenizer tries to, among other things, preserve email addresses.

What the effect of applying an algorithmic stemming process to words like you're interested in is...er...not obvious. All that said, I took a quick at the analysis page with your definition and nothing jumped out at me. Are you sure that: > you're getting to the request handler you think?

The SOLR admin page can help here, especially the [full interface] link, with debug info on. If nothing shows up, can you post the results of &debugQuery=on?
