-=head1 DESCRIPTION
+=head1 FUNCTIONS
 
 This module provides the searching facilities for the Koha MARC catalog
 
-C<&catalogsearch> is a front end to all the other searches. Depending
-on what is passed to it, it calls the appropriate search function.

+A field can be a list of fields : '200f','700a','700b','701a','701b'
+
+Example
+
+=head2 $and_or
+
+contains  a list of strings containing and or or. The 1st value is useless.
+
+=head2 $excluding
+
+contains 0 or 1. If 1, then the request is negated.
+
+=head2 $operator
+
+contains contains,=,start,>,>=,<,<= the = and start work on the complete subfield. The contains operator works on every word in the subfield.
+
+examples :
+contains home, search home anywhere.
+= home, search a string being home.
+
+=head2 $value
+
+contains the value to search
+If it contains a * or a %, then the search is partial.
+
+=head2 $offset and $length
+
+returns $length results, beginning at $offset
+
+=head2 $orderby
+
+define the field used to order the request. Any field in the biblio/biblioitem tables can be used. DESC is possible too
+
+(for example title, title DESC,...)
+
+=head2 RETURNS
+
+returns an array containing hashes. The hash contains all biblio & biblioitems fields and a reference to an item hash. The "item hash contains one line for each callnumber & the number of items related to the callnumber.
