Emacs employs fuzzy completion. That means that you only have to type a partial match that exists in anywhere in the result or even fragments of a partial match making for very flexible search. For example if I look for "filesystem" and yet I type"systemfile" or "sysfile" or "file-syse" etc, the search will still able to locate the "filesystem" packages and all its classes. 

I used this completion both for code completion and file path completion , but I am pretty sure it works everywhere inside emacs. 

That also mean a unified search for everything, classes, methods etc . Without of course ruling out focused search of any kind , regex and existing ways to search in Pharo. 

But I want to say that I am very happy we have this functionality in pharo. Thank you.

Another pponit about the search

it would be good to have the following behavior
        I type TOOLS

        I see all the packages with TOOLS

        I select one

        then I removed TOOLS from the search bar

        -> the selected package stays selected
