704 C<&CatSearch> searches the Koha catalog. It returns a list whose first
705 element is the number of returned results, and whose subsequent
706 elements are the results themselves.
708 Each returned element is a reference-to-hash. Most of the keys are
709 simply the fields from the C<biblio> table in the Koha database, but
710 the following keys may also be present:
716 The book's illustrator.
726 C<$type> may be C<subject>, C<loose>, or C<precise>. This controls the
727 high-level behavior of C<&CatSearch>, as described below.
729 In many cases, the description below says that a certain field in the
730 database must match the search string. In these cases, it means that
731 the beginning of some word in the field must match the search string.
732 Thus, an author search for "sm" will return books whose author is
733 "John Smith" or "Mike Smalls", but not "Paul Grossman", since the "sm"
734 does not occur at the beginning of a word.
736 Note that within each search mode, the criteria are and-ed together.
737 That is, if you perform a loose search on the author "Jerome" and the
738 title "Boat", the search will only return books by Jerome containing
741 It is not possible to cross modes, e.g., set the author to "Asimov"
742 and the subject to "Math" in hopes of finding books on math by Asimov.
746 If C<$type> is set to C<loose>, the following search criteria may be
751 =item C<$search-E<gt>{author}>
753 The search string is a space-separated list of words. Each word must
754 match either the C<author> or C<additionalauthors> field.
756 =item C<$search-E<gt>{title}>
758 Each word in the search string must match the book title. If no author
759 is specified, the book subtitle will also be searched.
761 =item C<$search-E<gt>{abstract}>
763 Searches for the given search string in the book's abstract.
765 =item C<$search-E<gt>{'date-before'}>
767 Searches for books whose copyright date matches the search string.
768 That is, setting C<$search-E<gt>{'date-before'}> to "1985" will find
769 books written in 1985, and setting it to "198" will find books written
770 between 1980 and 1989.
772 =item C<$search-E<gt>{title}>
774 Searches by title are also affected by the value of
775 C<$search-E<gt>{"ttype"}>; if it is set to C<exact>, then the book
776 title, (one of) the series titleZ<>(s), or (one of) the unititleZ<>(s) must
777 match the search string exactly (the subtitle is not searched).
779 If C<$search-E<gt>{"ttype"}> is set to anything other than C<exact>,
780 each word in the search string must match the title, subtitle,
781 unititle, or series title.
783 =item C<$search-E<gt>{class}>
785 Restricts the search to certain item classes. The value of
786 C<$search-E<gt>{"class"}> is a | (pipe)-separated list of item types.
787 Thus, setting it to "F" restricts the search to fiction, and setting
788 it to "CD|CAS" will only look in compact disks and cassettes.
790 =item C<$search-E<gt>{dewey}>
792 Searches for books whose Dewey Decimal Classification code matches the
793 search string. That is, setting C<$search-E<gt>{"dewey"}> to "5" will
794 search for all books in 5I<xx> (Science and mathematics), setting it
795 to "54" will search for all books in 54I<x> (Chemistry), and setting
796 it to "546" will search for books on inorganic chemistry.
798 =item C<$search-E<gt>{publisher}>
800 Searches for books whose publisher contains the search string (unlike
801 other search criteria, C<$search-E<gt>{publisher}> is a string, not a
806 =head2 Subject search
808 If C<$type> is set to C<subject>, the following search criterion may
813 =item C<$search-E<gt>{subject}>
815 The search string is a space-separated list of words, each of which
816 must match the book's subject.
818 Special case: if C<$search-E<gt>{subject}> is set to C<nz>,
819 C<&CatSearch> will search for books whose subject is "New Zealand".
820 However, setting C<$search-E<gt>{subject}> to C<"nz football"> will
821 search for books on "nz" and "football", not books on "New Zealand"
826 =head2 Precise search
828 If C<$type> is set to C<precise>, the following search criteria may be
833 =item C<$search-E<gt>{item}>
835 Searches for books whose barcode exactly matches the search string.
837 =item C<$search-E<gt>{isbn}>
839 Searches for books whose ISBN exactly matches the search string.
843 For a loose search, if an author was specified, the results are
844 ordered by author and title. If no author was specified, the results
845 are ordered by title.
847 For other (non-loose) searches, if a subject was specified, the
848 results are ordered alphabetically by subject.
