This is a shell level interface to WAIS questions
that have been built using xwais. It allows a user to submit questions
to sources for queries, and to retrieve documents from questions (and the
appropriate source). It can build or modify a question, including the modification
performed during a search.
[-f question_file] /* defaults to stdin, stdout */
[-s sourcedir] /* or ~/wais-sources/ */
[-c common_sourcedir] /* or it is ignored */
[-m max_Result_Docs] /* defaults to 40 */
[-g] /* to do a search */
[-h] /* this message */
[-t] /* test a source */
[-V] /* print version */

- -f question_filename
- the pathname for a question structure as stored in a file. It uses standard
UNIX conventions. If no filename is provided, stdin is used. If the filename
is a dash ( - ), no question will be read, so you must specify a sourcename
and the words to search. This will create a question structure and write
it to stdout.
- -s sourcedir
- a directory where source structures are stored.
It must end with a ’/’. If it is not specified, ~/wais-sources/ is used. If
none of those exist, the application will probably fail, unless the common_sourcedir
exists. Only files that end in .src in the directory are considered sources.
- -S sourcename
- the pathname of a source structure file. It must exist in
sourcedir or common_sourcedir, and end in .src
- -c common_sourcedir
to sourcedir, but usually common for a site. It need not exist.
- -m maxDocs
- The limit on the number of results returned by a server. Default value
- -v document_number
- The number of the document to retrieve from a valid
query. This can be from a previously stored question, or the current question
if the -g option is used.
- Test a source to see if it is servicing wais
requests. The first word will be taken as the name of a source.
the query. You must specify the -g option in order to actually perform a
query. You need not specify it if you have already performed a query from
which you wish to retrieve a document.
- Print the version number and date
of the program.
- optional search keywords to replace any search keywords
in the question.
- If the first argument is a dash ( - ) then waisq operates
in an interactive mode. It then reads question structures from standard
input, and returns results to standard output. If the question has search-words
or relevant documents, it performs the query, and returns the resulting
question structure to standard output. If there are only result documents,
it retrieves them and prints them to standard output. It continues to read
it’s input until an end of file is encountered, and then it exits. All other
command line switches will work, except -f. This makes waisq useful as a
tool for user interfaces to access the WAIS system.
- to create a
new question and submit it for a query:
waisq -f - -S sourcename -g word1 word2 > my_question
- to submit an existing
question for query:
waisq -f question_name -g
- To retrieve a response:
waisq -f question_name -v 1
