Retaining Last Search (Or History) When Clicking Search After A Search

Useful in that misspellings (especially that of long search strings) will be more easily corrected.

Otherwise you would have to autocomplete and click "Enter"...

[Lord of the Rings]

But you can repeat the previous search by right-clicking (for osx that's control-click) on any search result file & choosing Repeat Search.

And Autocomplete fulfills the other side of it. Just a thought. If this isn't what you mean please say.
