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

+of a number of places.
+
+C<&KeywordSearch> looks for keywords in the book title (and subtitle),
+series name, notes (both C<biblio.notes> and C<biblioitems.notes>),
+and subjects.
+
+C<$search-E<gt>{"class"}> can be set to a C<|> (pipe)-separated list of
+item class codes (e.g., "F" for fiction, "JNF" for junior nonfiction,
+etc.). In this case, the search will be restricted to just those
+classes.
+
+If C<$search-E<gt>{"class"}> is not specified, you may specify
+C<$search-E<gt>{"dewey"}>. This will restrict the search to that
+particular Dewey Decimal Classification category. Setting
+C<$search-E<gt>{"dewey"}> to "513" will return books about arithmetic,
+whereas setting it to "5" will return all books with Dewey code 5I<xx>
+(Science and Mathematics).
+
+C<$env> and C<$type> are ignored.
+
+C<$offset> and C<$num> specify the subset of results to return.
+C<$num> specifies the number of results to return, and C<$offset> is
+the number of the first result. Thus, setting C<$offset> to 100 and
+C<$num> to 5 will return results 100 through 104 inclusive.

+
+C<&CatSearch> searches the Koha catalog. It returns a list whose first
+element is the number of returned results, and whose subsequent
+elements are the results themselves.
+
+Each returned element is a reference-to-hash. Most of the keys are
+simply the fields from the C<biblio> table in the Koha database, but
+the following keys may also be present:
+
+=over 4
+
+=item C<illustrator>
+
+The book's illustrator.
+
+=item C<publisher>
+
+The publisher.
+
+=back
+
+C<$env> is ignored.
+
+C<$type> may be C<subject>, C<loose>, or C<precise>. This controls the
+high-level behavior of C<&CatSearch>, as described below.
+
+In many cases, the description below says that a certain field in the
+database must match the search string. In these cases, it means that
+the beginning of some word in the field must match the search string.
+Thus, an author search for "sm" will return books whose author is
+"John Smith" or "Mike Smalls", but not "Paul Grossman", since the "sm"
+does not occur at the beginning of a word.
+
+Note that within each search mode, the criteria are and-ed together.
+That is, if you perform a loose search on the author "Jerome" and the
+title "Boat", the search will only return books by Jerome containing
+"Boat" in the title.
+
+It is not possible to cross modes, e.g., set the author to "Asimov"
+and the subject to "Math" in hopes of finding books on math by Asimov.
+
+=head2 Loose search
+
+If C<$type> is set to C<loose>, the following search criteria may be
+used:
+
+=over 4
+
+=item C<$search-E<gt>{author}>
+
+The search string is a space-separated list of words. Each word must
+match either the C<author> or C<additionalauthors> field.
+
+=item C<$search-E<gt>{title}>
+
+Each word in the search string must match the book title. If no author
+is specified, the book subtitle will also be searched.
+
+=item C<$search-E<gt>{abstract}>
+
+Searches for the given search string in the book's abstract.
+
+=item C<$search-E<gt>{'date-before'}>
+
+Searches for books whose copyright date matches the search string.
+That is, setting C<$search-E<gt>{'date-before'}> to "1985" will find
+books written in 1985, and setting it to "198" will find books written
+between 1980 and 1989.
+
+=item C<$search-E<gt>{title}>
+
+Searches by title are also affected by the value of
+C<$search-E<gt>{"ttype"}>; if it is set to C<exact>, then the book
+title, (one of) the series titleZ<>(s), or (one of) the unititleZ<>(s) must
+match the search string exactly (the subtitle is not searched).
+
+If C<$search-E<gt>{"ttype"}> is set to anything other than C<exact>,
+each word in the search string must match the title, subtitle,
+unititle, or series title.
+
+=item C<$search-E<gt>{class}>
+
+Restricts the search to certain item classes. The value of
+C<$search-E<gt>{"class"}> is a | (pipe)-separated list of item types.
+Thus, setting it to "F" restricts the search to fiction, and setting
+it to "CD|CAS" will only look in compact disks and cassettes.
+
+=item C<$search-E<gt>{dewey}>
+
+Searches for books whose Dewey Decimal Classification code matches the
+search string. That is, setting C<$search-E<gt>{"dewey"}> to "5" will
+search for all books in 5I<xx> (Science and mathematics), setting it
+to "54" will search for all books in 54I<x> (Chemistry), and setting
+it to "546" will search for books on inorganic chemistry.
+
+=item C<$search-E<gt>{publisher}>
+
+Searches for books whose publisher contains the search string (unlike
+other search criteria, C<$search-E<gt>{publisher}> is a string, not a
+set of words.
+
+=back
+
+=head2 Subject search
+
+If C<$type> is set to C<subject>, the following search criterion may
+be used:
+
+=over 4
+
+=item C<$search-E<gt>{subject}>
+
+The search string is a space-separated list of words, each of which
+must match the book's subject.
+
+Special case: if C<$search-E<gt>{subject}> is set to C<nz>,
+C<&CatSearch> will search for books whose subject is "New Zealand".
+However, setting C<$search-E<gt>{subject}> to C<"nz football"> will
+search for books on "nz" and "football", not books on "New Zealand"
+and "football".
+
+=back
+
+=head2 Precise search
+
+If C<$type> is set to C<precise>, the following search criteria may be
+used:
+
+=over 4
+
+=item C<$search-E<gt>{item}>
+
+Searches for books whose barcode exactly matches the search string.
+
+=item C<$search-E<gt>{isbn}>
+
+Searches for books whose ISBN exactly matches the search string.
+
+=back
+
+For a loose search, if an author was specified, the results are
+ordered by author and title. If no author was specified, the results
+are ordered by title.
+
+For other (non-loose) searches, if a subject was specified, the
+results are ordered alphabetically by subject.
+
+In all other cases (e.g., loose search by keyword), the results are
+not ordered.
