  22 =head1 NAME
  23
  24 search - a search script for finding records in a Koha system (Version 3)
  25
  26 =head1 OVERVIEW
  27
  28 This script utilizes a new search API for Koha 3. It is designed to be
  29 simple to use and configure, yet capable of performing feats like stemming,
  30 field weighting, relevance ranking, support for multiple  query language
  31 formats (CCL, CQL, PQF), full support for the bib1 attribute set, extended
  32 attribute sets defined in Zebra profiles, access to the full range of Z39.50
  33 and SRU query options, federated searches on Z39.50/SRU targets, etc.
  34
  35 The API as represented in this script is mostly sound, even if the individual
  36 functions in Search.pm and Koha.pm need to be cleaned up. Of course, you are
  37 free to disagree :-)
  38
  39 I will attempt to describe what is happening at each part of this script.
  40 -- Joshua Ferraro <jmf AT liblime DOT com>
  41
  42 =head2 INTRO
  43
  44 This script performs two functions:
  45
  46 =over
  47
  48 =item 1. interacts with Koha to retrieve and display the results of a search
  49
  50 =item 2. loads the advanced search page
  51
  52 =back
  53
  54 These two functions share many of the same variables and modules, so the first
  55 task is to load what they have in common and determine which template to use.
  56 Once determined, proceed to only load the variables and procedures necessary
  57 for that function.
  58
  59 =head2 LOADING ADVANCED SEARCH PAGE
  60
  61 This is fairly straightforward, and I won't go into detail ;-)
  62
  63 =head2 PERFORMING A SEARCH
  64
  65 If we're performing a search, this script  performs three primary
  66 operations:
  67
  68 =over
  69
  70 =item 1. builds query strings (yes, plural)
  71
  72 =item 2. perform the search and return the results array
  73
  74 =item 3. build the HTML for output to the template
  75
  76 =back
  77
  78 There are several additional secondary functions performed that I will
  79 not cover in detail.
  80
  81 =head3 1. Building Query Strings
  82
  83 There are several types of queries needed in the process of search and retrieve:
  84
  85 =over
  86
  87 =item 1 $query - the fully-built query passed to zebra
  88
  89 This is the most complex query that needs to be built. The original design goal
  90 was to use a custom CCL2PQF query parser to translate an incoming CCL query into
  91 a multi-leaf query to pass to Zebra. It needs to be multi-leaf to allow field
  92 weighting, koha-specific relevance ranking, and stemming. When I have a chance
  93 I'll try to flesh out this section to better explain.
  94
  95 This query incorporates query profiles that aren't compatible with most non-Zebra
  96 Z39.50 targets to acomplish the field weighting and relevance ranking.
  97
  98 =item 2 $simple_query - a simple query that doesn't contain the field weighting,
  99 stemming, etc., suitable to pass off to other search targets
 100
 101 This query is just the user's query expressed in CCL CQL, or PQF for passing to a
 102 non-zebra Z39.50 target (one that doesn't support the extended profile that Zebra does).
 103
 104 =item 3 $query_cgi - passed to the template / saved for future refinements of
 105 the query (by user)
 106
 107 This is a simple string that completely expresses the query as a CGI string that
 108 can be used for future refinements of the query or as a part of a history feature.
 109
 110 =item 4 $query_desc - Human search description - what the user sees in search
 111 feedback area
 112
 113 This is a simple string that is human readable. It will contain '=', ',', etc.
 114
 115 =back
 116
 117 =head3 2. Perform the Search
 118
 119 This section takes the query strings and performs searches on the named servers,
 120 including the Koha Zebra server, stores the results in a deeply nested object,
 121 builds 'faceted results', and returns these objects.
 122
 123 =head3 3. Build HTML
 124
 125 The final major section of this script takes the objects collected thusfar and
 126 builds the HTML for output to the template and user.
