Thanks for your replies and sorry for my delayed reply.
"I bookmarked a webpage" means I use "Bookmark" functionality of "Clip to Evernote" extension of Chrome. The page I bookmarked is
When I searched for "ohio dey", the search results didn't include the note. When I searched for "ohio-state dey", the results looked similar. It seems that Evernote didn't index the source URL.
I have several recommendation for Webpage Evernote.
1. list the clip date in main text (I mean the right part the the page), along with source URL
2. distinguish bookmarks from common clips, otherwise there is meaningless to have a bookmark functionality in the "Clip to Evernote" extension.
