My ES project is coming along nicely but now I'd like more robust searches.

Given a single search field, perform logical AND's or OR's using a  
combination of the following:

1. quoted exact phrase searches. for example "this is a test"
2. prefixes such as "wiki:foo" or "-wiki:foo" which will include or  
exclude "foo" in documents of type "wiki"
3. if only a single number is entered, then do a term search on a  
specific field.

I'd like to leverage ES's out-of-the-box functionality as much as possible.

What's the best way to do the above customizations using the Java API?

Thanks

Use the query\_string query for it?
