If you're running 3.1.3, or earlier releases, htsearch won't accept
the query string as a command line argument - it must be passed as the
QUERY_STRING environment variable, with the REQUEST_METHOD environment
variable set to GET, as is done for CGI programs by convention.

In the 3.2 development version, htsearch will accept the query string
as a command line argument, for exactly this sort of application.
