Re: how to do exact serch with solrj
No, not text, but with that tokenizer + token filter I mentioned below. Anchors should not be needed if string is used, but the o.p. didn't want string, because he wanted lowercasing (or does string lowercase?) Of course, one could lowercase before indexing and use string type.

Re: how to do exact serch with solrj
I don't think there is anything ready to be used in Solr (but would be easy to add), but if you indexed your with a custom beginning of string and end of string anchors, you'll be able to get your exact matching working. For example, convert hello the world to $hello the world$ before indexing (and make sure you use string type or KeywordTokenizer -- things that won't remove any characters.
