C4::Search - Functions for searching the Koha catalog.

See opac/opac-search.pl or catalogue/search.pl for example of usage
=head1 DESCRIPTION
This module provides searching functions for Koha's bibliographic databases
=head1 FUNCTIONS

This function provides a simple search API on the bibliographic catalog
=over 2
=item C
* $query can be a simple keyword or a complete CCL query
* @servers is optional. Defaults to biblioserver as found in koha-conf.xml
* $offset - If present, represents the number of records at the beggining to omit. Defaults to 0
* $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
=item C
Returns an array consisting of three elements
* $error is undefined unless an error is detected
* $results is a reference to an array of records.
* $total_hits is the number of hits that would have been returned with no limit
If an error is returned the two other return elements are undefined. If error itself is undefined
the other two elements are always defined
