I was having trouble view Google Toolbar local search history past the most recent 15 entries. I have auto complete turned on so if I started typing a couple letters it would show older entries so I knew they existed. I figured the easiest way to get the entire list was to just go to the source file and view the entries there.
Google Toolbar Search History Location on Windows XP:
C:\Documents and Settings\user\Application Data\Google\Local Search History\google%2Eweb.w
Each user will have their own Google Toolbar local search history so just replace “user” in the directory path above to view each users local search history.
At first I attempted to open the above in Notepad++ but for some reason it thought it was another format of file and opened it in an unreadable format. Next I opened in Windows Notepad and it was listed in plain text however their were no line breaks included making it a pain to read. So the final solution was opening it in Windows Notepad, selecting all of the content, copying it to the clipboard, and then pasting it into Notepad++. Once you do this it will list each search on its own line from oldest to newest. The output doesn’t include the date or anything but if your just looking for an older search you more than likely know some of the content from the search string so you can just use the Find function to locate the search in question.
