This patch is to avoid hitting an error page. We should eventually make the max number returned configurable for ES. To test: 1 - Have Koha running ES with 10,000+ records 2 - Search for '*' 3 - Click 'Last' to view last page of results 4 - 'Cannot perform search' error 5 - Apply patch 6 - Search again 7 - View 'Last' page 8 - No error, you go to the last of 10000 9 - Note the warning above the pagination buttons Signed-off-by: Séverine QUEUNE <severine.queune@bulac.fr> Signed-off-by: Nick Clemens <nick@bywatersolutions.com> Signed-off-by: Alex Arnaud <alex.arnaud@biblibre.com> Signed-off-by: Nick Clemens <nick@bywatersolutions.com>

=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.
|
