  23 =head1 NAME
  24
  25 search - a search script for finding records in a Koha system (Version 3)
  26
  27 =head1 OVERVIEW
  28
  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.
  35
  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
  38 free to disagree :-)
  39
  40 I will attempt to describe what is happening at each part of this script.
  41 -- Joshua Ferraro <jmf AT liblime DOT com>
  42
  43 =head2 INTRO
  44
  45 This script performs two functions:
  46
  47 =over
  48
  49 =item 1. interacts with Koha to retrieve and display the results of a search
  50
  51 =item 2. loads the advanced search page
  52
  53 =back
  54
  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
  58 for that function.
  59
  60 =head2 LOADING ADVANCED SEARCH PAGE
  61
  62 This is fairly straightforward, and I won't go into detail ;-)
  63
  64 =head2 PERFORMING A SEARCH
  65
  66 If we're performing a search, this script  performs three primary
  67 operations:
  68
  69 =over
  70
  71 =item 1. builds query strings (yes, plural)
  72
  73 =item 2. perform the search and return the results array
  74
  75 =item 3. build the HTML for output to the template
  76
  77 =back
  78
  79 There are several additional secondary functions performed that I will
  80 not cover in detail.
  81
  82 =head3 1. Building Query Strings
  83
  84 There are several types of queries needed in the process of search and retrieve:
  85
  86 =over
  87
  88 =item 1 $query - the fully-built query passed to zebra
  89
  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.
  95
  96 This query incorporates query profiles that aren't compatible with most non-Zebra
  97 Z39.50 targets to acomplish the field weighting and relevance ranking.
  98
  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
 101
 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).
 104
 105 =item 3 $query_cgi - passed to the template / saved for future refinements of
 106 the query (by user)
 107
 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.
 110
 111 =item 4 $query_desc - Human search description - what the user sees in search
 112 feedback area
 113
 114 This is a simple string that is human readable. It will contain '=', ',', etc.
 115
 116 =back
 117
 118 =head3 2. Perform the Search
 119
 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.
 123
 124 =head3 3. Build HTML
 125
 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.
