Recall all - we are looking for in the user's bookmarks in parallel with the online search engine

Today I urgently needed a list of reserved words in VBA, the paper version was lost somewhere, I climbed into the net. The 3rd or 4th open link of course gave the necessary on MSDN. Just in case, I decided to throw it in the links, and, to my surprise, I found out that it already exists there, I just climbed out of habit into Google. This is not the first time with me - I add the site to the links, but I don’t need it often, and I just don’t remember that it’s there, and then I “find” it again. It’s like a disc lost in an apartment. It is easier to download from the Internet for a new one than to search it in the closets. It’s just here that I spent a minute, and other sites “migrated” after hours of searching.
Then I thought it would be good if the browser added a page to the bookmarks, saved its copy and then searched for these copies in parallel with the network search when prompted.

This approach will solve two problems:

• saves the user from having to search the site for a new one, if he suddenly forgot about his bookmark (and with 100+ bookmarks per year it is very easy).
• the user will be sure that he will have a copy of exactly the information that he saw on the site when laying it, because then the information from the site may be removed, and the link will become dead, and the info may be important to the user.

Mozilla’s native search for bookmarks in this matter didn’t help much - he only searches for a pair of “page title + link” and not the entire content of the page, and he’s hidden too deep in the menu to check his bookmarks with every request. In chrome has not yet looked.
