25 search - a search script for finding records in a Koha system (Version 3)
29 This script utilizes a new search API for Koha 3. It is designed to be
30 simple to use and configure, yet capable of performing feats like stemming,
31 field weighting, relevance ranking, support for multiple query language
32 formats (CCL, CQL, PQF), full support for the bib1 attribute set, extended
33 attribute sets defined in Zebra profiles, access to the full range of Z39.50
34 and SRU query options, federated searches on Z39.50/SRU targets, etc.
36 The API as represented in this script is mostly sound, even if the individual
37 functions in Search.pm and Koha.pm need to be cleaned up. Of course, you are
40 I will attempt to describe what is happening at each part of this script.
41 -- Joshua Ferraro <jmf AT liblime DOT com>
45 This script performs two functions:
49 =item 1. interacts with Koha to retrieve and display the results of a search
51 =item 2. loads the advanced search page
55 These two functions share many of the same variables and modules, so the first
56 task is to load what they have in common and determine which template to use.
57 Once determined, proceed to only load the variables and procedures necessary
60 =head2 LOADING ADVANCED SEARCH PAGE
62 This is fairly straightforward, and I won't go into detail ;-)
64 =head2 PERFORMING A SEARCH
66 If we're performing a search, this script performs three primary
71 =item 1. builds query strings (yes, plural)
73 =item 2. perform the search and return the results array
75 =item 3. build the HTML for output to the template
79 There are several additional secondary functions performed that I will
82 =head3 1. Building Query Strings
84 There are several types of queries needed in the process of search and retrieve:
88 =item 1 $query - the fully-built query passed to zebra
90 This is the most complex query that needs to be built. The original design goal
91 was to use a custom CCL2PQF query parser to translate an incoming CCL query into
92 a multi-leaf query to pass to Zebra. It needs to be multi-leaf to allow field
93 weighting, koha-specific relevance ranking, and stemming. When I have a chance
94 I'll try to flesh out this section to better explain.
96 This query incorporates query profiles that aren't compatible with most non-Zebra
97 Z39.50 targets to accomplish the field weighting and relevance ranking.
99 =item 2 $simple_query - a simple query that doesn't contain the field weighting,
100 stemming, etc., suitable to pass off to other search targets
102 This query is just the user's query expressed in CCL CQL, or PQF for passing to a
103 non-zebra Z39.50 target (one that doesn't support the extended profile that Zebra does).
105 =item 3 $query_cgi - passed to the template / saved for future refinements of
108 This is a simple string that completely expresses the query as a CGI string that
109 can be used for future refinements of the query or as a part of a history feature.
111 =item 4 $query_desc - Human search description - what the user sees in search
114 This is a simple string that is human readable. It will contain '=', ',', etc.
118 =head3 2. Perform the Search
120 This section takes the query strings and performs searches on the named servers,
121 including the Koha Zebra server, stores the results in a deeply nested object,
122 builds 'faceted results', and returns these objects.
126 The final major section of this script takes the objects collected thusfar and
127 builds the HTML for output to the template and user.
