Let’s start by clarifying something important: search history tracks your last four searches on this computer and with this particular web browser. For example, suppose you conduct searches A, B, C, and D on your desktop workstation using Chrome, then log on to your laptop computer and conduct searches E, F, G, and H (again using Chrome). When you return to your desktop machine, the search history will consist of the last four searches that took place on that computer: A, B, C, and D.
And on your laptop? That’s right: you’ll see searches E, F, G, and H, the four searches conducted on that computer. Searches are stored locally: they are not stored in a central location accessible from any computer and/or any web browser.
Here’s a more visual example of what we’re talking about. Suppose we log on to Computer 1 and search for all the users who live in the US. That search gets added to our search history:
If we now log onto Computer 2 and check our search history, we won’t see anything at all:
Why not? You got it: because we haven’t conducted any searches on Computer 2. If we run a search on Computer 2, that search will be added to Computer 2’s search history, but it won’t be added to the search history for Computer 1.
But don’t go away just yet: there’s more. As noted, search histories also differ depending on your web browser. For example, log on to the Console using Chrome, and do searches A, B, C, and D. After that, and on the same computer, log on to the Console using Safari. Searches A, B, C, and D will not be visible in Safari, even though the browser is on the same computer as Chrome. That’s because the search history is maintained in local storage for each browser. If you take a look at local storage on Chrome, you can see that for yourself. Chrome might have a search history info that looks like this:
Meanwhile, Safari’s local storage will contain a different search history:
Two different search histories, one for each browser.
