Benson,

it was in the Lucene world in May 2010:

Mark Harwood pointed me to a "FlagQuery" which was exactly what I needed.
His contribution sounds not to have been taken up, it worked for me in Lucene, 
2.4.1.
We used this to create an auto-completion popup which selected the right 
language by flagging the right sub-query that was most matched.
