display outline headings up to certain level in search-view

display outline headings up to certain level in search-view

Hi,

Let's say I have an org file structured like this

* Project 1
** Tasks
   foo
** Ideas

* Project 2
** Tasks
   bar

When I search 'foo' I'd like the agenda search-view to display 'Project
1' instead of the closer, but less informative 'Tasks'

The attached patch solves this by adding a configuration parameter that
sets the maximum outline level for the headings displayed in the results
of a search-view. This way, I can have a custom search on the above org
file with org-agenda-search-view-max-outline-level set to 1.

Abdó Roig.

Subject: [PATCH] set max level to display in search-view results

* lisp/org-agenda.el (org-search-view) Adds the config setting
  org-agenda-search-view-max-outline-level that limits the depth of
  items on an agenda-search-view results. When a match is found,
  displays the innermost outline heading containing the match such
  that its level does not exceed
  org-agenda-search-view-max-outline-level.

Thanks.  I've applied your patch with a few some cosmetic changes.

I hesitated before applying this patch because maybe we want this for
other agenda views as well.  But after some thinking, I see how this
is useful for search views and I'm not sure whether this would be useful
for other agenda views.

Best,
