You can click the little magnifying glass icon in the search box at the bottom of the main window to restrict your search to a particular part of the event list.
|File pathname||Sonar will search in the the File column. It will search both the name of the file and the name of every containing folder. You can also search for portions of a path. For example, you can search for "Library/Preferences" to find changes inside your preferences folder.|
|Event type||Sonar will search the Event column.|
|Process||Sonar will search the Process column, which shows the name of the process (program or application) that generated the event. The process name is not available for every event because sometimes the process quits before the file system can look up its name.|
|Anywhere||Sonar will search in the File, Event and Process columns.|
