The GUI is organized in two new tabs that will have their switch buttons on top of the panes.

The Contents tab is for navigation of installed docs and it is exactly the same as the current content list pane in Nautilus.
 
 
 

The Index tab displays an index depending on the toggle setting of "Show indexes for:". If "Selection on Contents tab" is selected then it displays the index of the doc selected in the Contents tab. The natural way of events should be that the user selects a doc in the Contents pane and then switches to the Index pane. This will select the toggle "Selection on Contents tab" and display the selected doc index.

If "All documents" is selected then indexes of all docs that Nautilus knows about will be displayed. If "Specific documents" is selected then the user will have to click on the button near the toggle, this will replace the index view with a content list view (image 3, right) and the user will have to select docs or groups of docs there. When returning from that only indexes of selected docs will be displayed.

The second set of toggles in the Index pane allows filtering the indexes displayed. It is self-explanatory, and very simple, no boolean combination of several keywords is allowed. Typing more than one word and searching for them as they are should be ok though.

We don't think it is realistic to try to implement text body search for Gnome 2.0, but when this will be done it will have to be done probably in a separate pane.
