i think that would have to be *tsdb-maximal-number-of-analyses* rather,
and you would have to set it in the master [incr tsdb()] process, which
will pass on its current value to the processing clients.  however, the
on-line demonstrator controls for exhaustive vs. n-best search predated
the introduction of selective unpacking, and so parsing and generation
always performed an exhaustive search.  which was silly, and i have now
changed the code to run in n-best mode by default.  this means improved
efficiency and potentially better ranking.

furthermore, the `show: X results' control did not apply to generation,
so no matter what you did it would use the default value of 5.  i have
just changed this behavior, so please give the latest version a try.
