# 20000501 Kevin Kinnell : Changed to support new search functionality.
#                          Move a block of code to wikisearch.pm, removed
#                          hardcoded flags (except the inline flag) from
#                          the searchWikiWeb call, added new params.
#
# 20020325 Jerome Bouvattier : 
#                          Added unescaping of url encoded params
#                          Enabled support for FormattedSearch params

    # The CGI.pm docs claim that it returns all of the values in a
    # multiple select if called in a list context, but that may not
    # work (didn't on the dev box -- perl 5.004_4 and CGI.pm 2.36 on
    # Linux (Slackware 2.0.33) with Apache 1.2.  That being the case,
    # we need to parse them out here.

    # Note for those unused to Perlishness:
    # -------------------------------------
    # The pipeline at the end of this assignment splits the full query
    # string on '&' or ';' and selects out the params that begin with 'web=',
    # replacing them with whatever is after that.  In the case of a
    # single list of webs passed as a string (say, from a text entry
    # field) it does more processing than it needs to to get the
    # correct string, but so what?  The pipline is the second
    # parameter to the join, and consists of the last two lines.  The
    # join takes the results of the pipeline and strings them back
    # together, space delimited, which is exactly what &searchWikiWeb
    # needs.
    # Note that mod_perl/cgi appears to use ';' as separator, whereas plain cgi uses '&'
