In some cases, a single headword entry can relate to a large number of
topics.  I have tried dealing with longer tag lists: automatic adjustment of
tags column (on this list a little utility was posted:
org-adjust-tags-column-reset-tags.  I THINK that a keyword list may allow
more freedom to cross-index, especially if it is easy to use.

Can someone suggest a way to implement a keywording system, perhaps with a
custom agenda search?  Or have others dealt with this issue in innovative
ways?

I would appreciate any ideas.
