This lays the foundation for further changes for report 7310. Implements following points from the wiki page List permissions: 1) Preference that controls if users may create public lists in opac. 2) New add/delete own/delete other permissions per list. Code has been changed (in some cases refactored). New permissions are not yet visible; with this patch current functionality is kept as much as possible while resolving several issues, improving permissions and extending the code for further developments (using the new permissions and sharing lists). Feb 23, 2012 (revision): Changed defaults for new lists. Could also remove routine GetRecentShelves by using GetSomeShelfNames in catalogue/search.pl just as opac-search.pl already did. (More consistent.) Signed-off-by: Jared Camins-Esakov <jcamins@cpbibliography.com> Feb 29, 2012: Automerge version. March 5, 2012: Rebase for pushed 4912 patch. March 21, 2012: Rebased. Resolving some conflicts in relation to pushed report 7719.

=head1 NAME
|
|
|
|
search - a search script for finding records in a Koha system (Version 3)
|
|
|
|
=head1 OVERVIEW
|
|
|
|
This script utilizes a new search API for Koha 3. It is designed to be
|
|
simple to use and configure, yet capable of performing feats like stemming,
|
|
field weighting, relevance ranking, support for multiple query language
|
|
formats (CCL, CQL, PQF), full support for the bib1 attribute set, extended
|
|
attribute sets defined in Zebra profiles, access to the full range of Z39.50
|
|
and SRU query options, federated searches on Z39.50/SRU targets, etc.
|
|
|
|
The API as represented in this script is mostly sound, even if the individual
|
|
functions in Search.pm and Koha.pm need to be cleaned up. Of course, you are
|
|
free to disagree :-)
|
|
|
|
I will attempt to describe what is happening at each part of this script.

|
|
|
|
=head2 INTRO
|
|
|
|
This script performs two functions:
|
|
|
|
=over
|
|
|
|
=item 1. interacts with Koha to retrieve and display the results of a search
|
|
|
|
=item 2. loads the advanced search page
|
|
|
|
=back
|
|
|
|
These two functions share many of the same variables and modules, so the first
|
|
task is to load what they have in common and determine which template to use.
|
|
Once determined, proceed to only load the variables and procedures necessary
|
|
for that function.
|
|
|
|
=head2 LOADING ADVANCED SEARCH PAGE
|
|
|
|
This is fairly straightforward, and I won't go into detail ;-)
|
|
|
|
=head2 PERFORMING A SEARCH
|
|
|
|
If we're performing a search, this script performs three primary
|
|
operations:
|
|
|
|
=over
|
|
|
|
=item 1. builds query strings (yes, plural)
|
|
|
|
=item 2. perform the search and return the results array
|
|
|
|
=item 3. build the HTML for output to the template
|
|
|
|
=back
|
|
|
|
There are several additional secondary functions performed that I will
|
|
not cover in detail.
|
|
|
|
=head3 1. Building Query Strings
|
|
|
|
There are several types of queries needed in the process of search and retrieve:
|
|
|
|
=over
|
|
|
|
=item 1 $query - the fully-built query passed to zebra
|
|
|
|
This is the most complex query that needs to be built. The original design goal
|
|
was to use a custom CCL2PQF query parser to translate an incoming CCL query into
|
|
a multi-leaf query to pass to Zebra. It needs to be multi-leaf to allow field
|
|
weighting, koha-specific relevance ranking, and stemming. When I have a chance
|
|
I'll try to flesh out this section to better explain.
|
|
|
|
This query incorporates query profiles that aren't compatible with most non-Zebra
|
|
Z39.50 targets to acomplish the field weighting and relevance ranking.
|
|
|
|
=item 2 $simple_query - a simple query that doesn't contain the field weighting,
|
|
stemming, etc., suitable to pass off to other search targets
|
|
|
|
This query is just the user's query expressed in CCL CQL, or PQF for passing to a
|
|
non-zebra Z39.50 target (one that doesn't support the extended profile that Zebra does).
|
|
|
|
=item 3 $query_cgi - passed to the template / saved for future refinements of
|
|
the query (by user)
|
|
|
|
This is a simple string that completely expresses the query as a CGI string that
|
|
can be used for future refinements of the query or as a part of a history feature.
|
|
|
|
=item 4 $query_desc - Human search description - what the user sees in search
|
|
feedback area
|
|
|
|
This is a simple string that is human readable. It will contain '=', ',', etc.
|
|
|
|
=back
|
|
|
|
=head3 2. Perform the Search
|
|
|
|
This section takes the query strings and performs searches on the named servers,
|
|
including the Koha Zebra server, stores the results in a deeply nested object,
|
|
builds 'faceted results', and returns these objects.
|
|
|
|
=head3 3. Build HTML
|
|
|
|
The final major section of this script takes the objects collected thusfar and
|
|
builds the HTML for output to the template and user.
|
|
