org-velocity only returns top-level headlines?

[Adam Porter <adam@alphapapa.net>]

Hi,

I'm using org 8.0.7 and I just installed org-velocity from git master.  It
seems to work, but when searching, it only displays top-level headlines. 
For example, I have a log.org file with a datetree like this:

* 2013
** 2013-07 July
*** 2013-07-19 Friday
**** Found a peanut last night
*** 2013-07-24 Wednesday
...
*** 2013-07-31 Wednesday

When I use org-velocity-read to search for Wednesday, it shows one result
that looks like this:

2013 ** 2013-07 July *** 2013-07-19 Friday ****...

Instead of showing individual subheadings that match the search, it flattens
the tree to the top-level headline and shows a single result.  It seems to
me that it should show a list of results like this:

*** 2013-07-24 Wednesday
*** 2013-07-31 Wednesday

I've looked through the page on Worg, the org-velocity customize group, the
comments in org-velocity.el, and posts on this list, but this behavior
doesn't seem documented.  I looked through the elisp code and saw where it
seems to only match top-level headlines, but I don't understand why it's
written that way.  It claims to support navigating any and all org files,
but since it only matches top-level headings, it doesn't seem very useful
for that.

Am I missing something?  Is there a simple way to change it to match
subheadings?

Thanks.
