35 dictionnary.pl : script to search in biblio & authority an existing value
36
37 =head1 SYNOPSIS
38
39 useful when the user want to search a term before running a query. For example, to see if "computer" is used in the database
40
41 The parameter "marclist" tells which field is searched (title, author, subject, but could be anything else)
42
43 This script searches in both biblios & authority
44 * in biblio, the script search in all marc fields related to what the user is looking for (for example, if the dictionnary is used on "author", the script searches in biblio.author, but also in additional authors & any MARC field related to author (through the "seealso" MARC constraint)
45 * in authority, the script search everywhere. Thus, the accepted & rejected forms are found.
46
47 The script shows all results & the user can choose what he want, that is copied into search form.
