Update of /cvsroot/koha/koha/opac
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv15229/opac
Added Files:
opac-search-biblio.pl
Log Message:
two new files
SearchBiblio.pm forked from SearchMarc.pm
opac-search-biblio.pl forked from opac-search.pl (just change module)
an attempt at a new search using FULLTEXT indexes.
NB: Boolean won't work without MySQL >v4.0
NNB: Will be slow without indexes added on Biblio table as follows:
ALTER TABLE biblio ADD FULLTEXT (author,title,unititle,seriestitle);
Only searching on "Any word" field just now.
more to come.

### Added by JF
## This next does a number of things:
# 1. It allows you to track all the searches made for stats, etc.
# 2. It fixes the 'searchdesc' variable problem by introducing
# a. 'searchterms' which comes out as 'Keyword: neal stephenson'
# b. 'phraseorterm' which comes out as 'neal stephenson'
# both of these are useful for differen purposes ... I use searchterms
# for display purposes and phraseorterm for passing the search terms
# to an external source through a url (like a database search)
# 3. It provides the variables necessary for the spellchecking (look below for
# how this is done
# 4.
