For example:
I have 45 notes with tag "eBook - Javascript" but when I choose from a note "Filter by tag"", evernote return only 2 notes.
This is a bug.
When I choice a tag from menu like filter, evernote found only the last note and not all. When I search like that "tag:name of tag", evernote return all the notes that have that tag.
Additional, when I do this from "evernote web", all working right
