> There is excellent documentation for how to use the Filter Language (including examples!),
implemented in HBASE-4176. Unfortunately, it's [hidden|http://hbase.apache.org/book/thrift.html#thrift.filter-language]
as the only section in the otherwise empty Thrift chapter. I suggest it be moved to it's own
appendix and referenced by all the places that expose it (currently just Thrift and the Shell,
eventually REST -- pending completion of HBASE-5417).
