server-side filtering with mongoose-datatable

I'm using the jQuery datatable with Node and MongoDb, and I found a tool mongoose-dataTable to deal with that. But I can't figure out how to implement filtering on certain columns.

Is bChunkSearch the clue to that? I've tested it on Demo Repository and I tried to send a query string:

localhost:3000?bChunkSearch:true

localhost:3000?name:Pam

in order to filter the name column with Pam, but it seems not working. Does anyone know how to do it? Thanks!!
