History Filter Field
When only the history entries that contain a specified substring need to be displayed in the History view, the filter field displayed at the top of this view is a useful tool. Just enter the search string in the field next to the Find label. Only the items (with an author name, commit message, revision number, or date) that match the search string are kept in the History view. When you press the Search button, the filter action is executed and the content of the table is updated.
