Dan, <br>
Yes thanks. That was exactly what I was looking for.<br>
I would suggest that your second paragraph (probably with little to
no change) be added to the Declarative Module section of the
reference-manual.doc. Maybe on page 201 right before the section on
Activation. What do you think?<br>

<pre wrap="">All,
I have been looking for a detailed discussion of how a retrieval
request "+retrieval>" functions for chunk-type supertype matches (or
subytpe matches).
I have not been able to find any such discussion (in archives,
tutorials, or reference manual).
Can anyone steer me in the right direction?
My questions are:
Thank you,
Stu

It looks like your specific questions got clipped, but there's not
really anything special about it so hopefully this general info
will help.
To be retrieved, a chunk must be a subtype of the chunk-type specified
in the retrieval request (a chunk-type is considered to be a subtype of
itself). That's basically all there is to it. There is no penalty or
bonus to the activation of the possible matches based on the specific
chunk-type of a chunk in the retrieval set.
For more details of the matching you can look at the match-chunk-spec-p
and find-matching-chunks commands in the reference manual. Essentially,
the declarative module uses find-matching-chunks with the default testing
functions and the set of all chunks in DM to determine which chunks are a
match.
Hope that helps,
Dan
