[Tracker] How do I get to see a the context of Search results using the CLI?

["Baz Jenner \(F2S\)" <bazjenner f2s com>]

When using tracker from the GUI, results come back with the file path etc
and a small extract of the text to give the searched term some context.

How do I get the same results using the GUI?  Are the verbose levels in the
config files the right ones to change?
