# This is a wrapper script called by a generic "search" box, that can 
# perform different functions based on the "name" value
# searched text is in var "search"
#  all - Search in all webs
#  webs - search in a group of webs, space-separated list in var web
#  web - search only one web, name in var web (and current web in URL)
#  topicname - search for a topic name in current web
#  goto - go to topic of name
#  create - create topic of name
#  forcecreate - create topic of name, even if not in WikiName notation

# debug
# test by something like:
#  curl -i -S -d 'Search+By=Main+webs&search=foo&Go=Search' http://koala.ilog.fr/wiki/bin/searchmulti/Main
