Hi Peter,
as you have seen, changing the logic is not easy, for a number of
reasons.
I would like to have parenthesis, but since the parsing is done by
string processing, any parenthesis in one of the search strings would
be difficult to handle.
Some work-arounds:
1. Have you thought about using a sparse tree? Or is you stuff in
different files?
2. You could use categories to mark the entries. Basically make each
project its own category.
3. Have you tried follow mode in the agenda? Then you will always
see, in another window, the embedding of the entry you are looking at.

I only discovered org-mode a couple of weeks ago, so apologies if this
is a FAQ, or the patch is in the wrong format.
I would like to define an agenda command to show TODO items in the
context of the projects to which they belong, like this:
todo: .Widget project
todo: ..TODO Gather widget requirements
todo: .Gadget project
todo: ..TODO Plan the end of project party
That would be a search like:
(LEVEL=2) | (/TODO)
But LEVEL=2|/TODO is interpreted as (LEVEL=2|) & (/TODO)
because / has the lowest precedence.
/TODO|LEVEL=2 treats LEVEL as a TODO word instead of a tag.
Is there any way around this, short of implementing parentheses?
One possibility might be to make operators that are like / but bind
most
tightly, one to say "this is a todo keyword" and one to say "this is a
tag". For instance, if \ was like / but high precedence, and % was the
opposite of \, my query would become:
\TODO | %LEVEL=2
Having looked at the code, that looks almost as hard as parens.
Next idea: since "/" means "and this TODO expression", add "\" meaning
"or this TODO expression". So my query becomes:
LEVEL=2\TODO
This is a lot easier to implement. In fact, this patch does it:
