How apply filter on remote data

[Jijo]

We are using remote data to create treeview, so our tree data type is

public treedata: Observable<any>;

So in search function we are getting exception

Argument of type 'Observable<any>' is not assignable to parameter of type 'any[]'.

How we apply a filter on remote async data?
