Mongoose optional search query parameters?

Question

I have a following situation. I need to build a mongoose query, based on certain arguments if present.

I.e. if object like this is passed

{
    playe

Build up your query object programmatically:

var query = {
    player: 'player'
};

if (obj.action) {
    query.action = obj.action;
}

Entry.find(query).exec(function(err, res){
    console.log(res);
});
