Are all those asterisk characters (*) really part of that code? If any of
them are for emphasis, please send your code again, but do it clean, and
don't use HTML or rich text email.
A query of * is not valid syntax. For all docs with edismax, set a blank
query string and set the q.alt parameter to the *:* special string for all
docs. It's best to set q.alt in the handler definition, but you can do it
as a param with SolrJ too.

This time you've got the *:* in there, but with extra asterisks that may
or may not actually be there in the code, as mentioned previously. I'm
reading this on a text mail client, so if you've used fonts, colors, or
attributes like bold/italic, I can't see them. Also, unless the edismax
parameter for lowercase operators is true, "or" must be "OR" for it to
work. That parameter may default to true, I'm not sure.
The OR clause is unnecessary. Asking for "all documents OR a subset of
documents" will always return all documents.
If you want to affect the order of documents, you need to use boosting.
Perhaps a bq param set to "code:888^100" would work? You might need to
adjust the 100 value up or down.
Thanks,
