My notes are very long and most are articles, PDF etc. The issue is that Evernote is starting an incremental search after first couple of letters. If I create the search argument externally to Evernote and simply "cut and paste" it into the search field (for example, Intitle:"frank mundo" the search proceeds very fast. What is needed is an option in settings to not initiate the search until user hits ENTER or clicks out of the search field.
