A copy field does not address my problem, and this has nothing to do with stored fields. This is a query parsing problem, not an indexing problem.
Here's the use case. If someone has a username like "bob-smith", I would like it to match prefixes of "bo" and "sm". I tokenize the username into the tokens "bob" and "smith". Everything is fine so far. If someone enters "bo sm" as a search string, I would like "bob-smith" to be one of the results. The query to do this is straight forward, "username:bo* username:sm*". Here's the problem. In order to construct that query, I have to tokenize the search string "bo sm" **on the client**. I don't want to reimplement tokenization on the client. Is there any way to give Solr the string "bo sm", have Solr do the tokenization, then treat each token like a prefix?
