Removing past searches from Google Chrome's omnibar

The term Orange Juice is stored in the C:\Users\{username}\AppData\Local\Google\Chrome\User Data\Default folder for Windows 7, and in /Users/{username}/Library/Application Support/Google/Chrome/Default for Mac OS X, inside a SQLite database file named History (no file extension), in a table called keyword_search_terms. If you're looking to change URL predictions, the table is called 'urls'.

You need to make sure Chrome is not running, so open this page in another browser.

Next, download a SQLite database browser such as SQLite Browser (recommended for OS X), or the Firefox addon SQLite Manager.

With the Firefox addon, you can click on Explorer's address bar and paste %LOCALAPPDATA%\Google\Chrome\User Data\Default to quickly get to that folder.

SQLite browser doesn't show you the hidden files & folders you need on mac. You can choose "Go To Folder..." and paste the path to have the folder opened, or you can go to Finder and have all hidden files/folders shown. Follow these steps to show them. Then go to /Users/YourMacUsername/Library/Application Support/Google/Chrome. Drag the 'Default' Folder to the sidebar as a shortcut. Then, in SQLite browser, click the open folder icon in the top left, and then the default folder in the finder sidebar. Select the file named 'History' with no file extension. Then find and go to 'Browse Data'.

Next, open up the keyword_search_terms table, and in the lower_term column, find Orange Juice delete the row and save changes. For URL predictions, open up the urls table and remove entries.

If you want to do this in one command, SQLite can run SQLite SQL scripts, too. Something like DELETE FROM keyword_search_terms WHERE lower_term = 'orange juice'.

Instead of going into Options to delete entries, you can also delete history by hitting CTRL+H:

The Shortcuts Database also has a reference that will pull up the recommendation if you dont go clear it as well.
