This was part of the rationale for introducing the XML Query Parser:

1) An extensible query syntax that is expressive enough to represent the full range of Lucene
functions (filters, moreLikeThis etc)
2) Serializable
3) Language independent
4) Decouples the holder of query criteria from the  implementations that execute the query.

Although I am curious about this myself, couldn't you just send a query string?
