If you haven't modified your schema.xml, you'll find that the <defaultSearchField> is set to the text field. So when you issue the q=term you're going against your default search field.
Assuming you've changed the default search field to "defaultSearch", then the problem is probably that your analysis chain for default search is different from that applied to your individual fields. Which I absolutely guarantee since you have two different fieldTypes in your 5 fields. I'm extremely suspicious of your fieldTypes that involve the word "keyword", because if this indicates the KeywordTokenizer is being used, then everything in the input is a single token, the input stream isn't being split up... But the best way to understand this is in the admin/analysis page. If you check the "verbose" box and put in some text you'll see the effects of each part of the chain. Try this for the field you expect Dismax to find your term in, and also for your defaultSearch field and I suspect you'll see what's going on....
