The commands given by Tim and (with slight variation) by me will fold
away _all_ lines not containing the search text, with no context. To get
context, you could use diff instead, as follows:
:split
:saveas ~/difftemp
:%g/searchtext/d
:wall
:!diff -u % # >temp.diff
Then the file "temp.diff" in the current directory will display all
lines containing the search text, with some context above and below each
group. (Lines containing the search text have a + in the left margin,
omitted lines are clearly set off.) Of course this requires a "diff"
program in your PATH, which is standard on Unix but not on Windows.
Replace -u by (for instance) -U6 to get (let's say) six lines of context
instead of the default three.
Best regards,
Tony.
