Hi Aaron,

I was about to make you a sample on how to build a pipe that does what you 
need. However, while preparing that I did reread the (apparently quite 
updated) pipe docs. 
Here is a quote from the docs 
<https://angular.io/docs/ts/latest/guide/pipes.html>:

No FilterPipe or OrderByPipe
> Angular does not ship with pipes for filtering or sorting lists. 
> Developers familiar with Angular 1 know these as filter and orderBy. There 
> are no equivalents in Angular 2.
> This is not an oversight. Angular 2 is unlikely to offer such pipes 
> because (a) they perform poorly and (b) they prevent aggressive 
> minification.
> Both filter and orderBy require parameters that reference object 
> properties. We learned earlier that such pipes must be impure 
> <https://angular.io/docs/ts/latest/guide/pipes.html#pure-and-impure-pipes> 
> and that Angular calls impure pipes in almost every change detection cycle.
> Filtering and especially sorting are expensive operations. The user 
> experience can degrade severely for even moderate sized lists when Angular 
> calls these pipe methods many times per second. The filter and orderBy have 
> often been abused in Angular 1 apps, leading to complaints that Angular 
> itself is slow. That charge is fair in the indirect sense that Angular 1 
> prepared this performance trap by offering filter and orderBy in the first 
> place.


If you after reading the last few paragraphs of the (linked above) docs 
still want a filter_filter pipe, I will prepare a sample for you. 

Regards
Sander
