I am trying to add a folder of large text files to the Digital Librarian on
a NeXT.  I cannot find any sufficient documentation for doing this, so the
process I used is as follows:

-drag the folder icon from the browser to an empty window in the DL
-select the new entry as the target
-select targets from the DL menu
-select index info... from the targets menu
-click on create index

The files I am trying to index are very large, but not as big as the works
of Shakespeare.  Yet, the DL locked up the first time I tried this, and the
second time it completed the index but the index exceeded 18MB!!  The index
on Shakespeare is less than 4MB.  What am I doing wrong?

Furthermore, the first time I tried to do a search on the newly created index,
the system locked up.  I used the control-control-~ keys to see what msgs
were being sent.  The following was repeated many times:

  >IO error on pageout: error=28
  >vnode_pageout: failed!

Any hints or suggestions as to what is happening?

I have also ventured into the realm of creating icons.  This is no easy
task since icons for the DL must be created upside down and inverted.  What
is the reasoning behind this?  Is this some kind of joke?  I was able to
create an icon and assign it to the entry I added to the DL by adding a line
to the .targets file.  That was simple enough, but not very intuitive.

My biggest complaint about the NeXT is the lack of thorough documentation and
the need for non-UNIX ways to handle problems/errors.  I know, I know--this is
still beta system software and 1.0 will be the answer to all problems.  I
guess I'll have to wait and see....  Another problem is that there is no
indicator light to show when the printer is receiving data or when the hard
disk is being accessed.

Onward...
