Changes by: Chris Cormack <address@hidden> 06/02/13 21:03:21
Modified files:
C4 : Search.pm
Log message:
Start of the complete rewrite of Search.pm
It just does a simple cql search at the moment, takes a hashref of
keyed by variable.
I have introduced 2 new variables to koha.conf
zebraserver and zebraport Ill add to the installer to get these set.
Very very very much a work in progress still. Thanks to paul for
getting things up to this point.

-C<&KeywordSearch> searches the catalog by keyword: given a string
-(C<$search-E<gt>{"keyword"}> consisting of a space-separated list of

-
-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

-
-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.
