Add a test with more tags for notes:withTags:

[Ducasse]

Point 1 More tests

testNotesWithTags

	| result |
	ressources addingNotesAndTagsTo: noteTakerContainer.

	result := noteTakerContainer
		          notes: noteTakerContainer notes
		          withTags: (OrderedCollection new
				           add: (noteTakerContainer ensureTagNamed: 'test');
				           yourself).
	self assert: result size equals: 0.

	result := noteTakerContainer
		          notes: noteTakerContainer notes
		          withTags: (OrderedCollection new
				           add: ressources getTag1;
				           yourself).
	self assert: result size equals: 1

Point 2: rename method

In addition notes:withTags: could be interpreted as a setter
-> rename it for example selectNotes:withTags:

Point 3: is argument really needed?

Question why the container is needed to get a collection of notes? Why does not work on its notes.
Why the method is not just selectWithTags:?

Ok the answer is probably here

filter

	| filteredItems |
	filteredItems := searchBar text
		                 ifEmpty: [ self notes ]
		                 ifNotEmpty: [ :pattern |
		                 self model notesContentsMatching: pattern ].

	filteredItems := filteredTagsSelection
		                 ifEmpty: [ filteredItems ]
		                 ifNotEmpty: [ :pattern |
			                 self model
				                 notes: filteredItems
				                 withTags: filteredTagsSelection ].

	self items: filteredItems
