When you left click on a Monotone Browser window's Find Files button you will be presented with a window like the one shown below.
This window is split into two distinctive areas:
Query - This panel allows one to enter fairly complex search criteria and perform file searches. The behaviour of this panel should be familiar to anyone that has used a similar facility inside a file manager.
Results - This panel displays a list of files that match the query. The information fields at the bottom display the same sort of information as that displayed in a Monotone Browser's File Viewer panel (see Section 2.5.4) apart from the File id field, which displays the selected file's unique Monotone id.
