+=head1 NAME
+
+search - a search script for finding records in a Koha system (Version 3.0)
+
+=head1 OVERVIEW
+
+This script contains a new search API for Koha 3.0. 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 or nearly full support for the
+bib1 attribute set, extended attribute sets defined in Zebra profiles, access
+to the full range of Z39.50 query options, federated searches on Z39.50
+targets, etc.
+
+I believe 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.
+-- JF
+
+=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 THE ADVANCED SEARCH PAGE
+
+If we're loading the advanced search page this script will call a number of
+display* routines which populate objects that are sent to the template for
+display of things like search indexes, languages, search limits, branches,
+etc. These are not stored in the template for two reasons:
+
+=over
+
+=item 1. Efficiency - we have more control over objects inside the script,
+and it's possible to not duplicate things like indexes (if the search indexes
+were stored in the template they would need to be repeated)
+
+=item 2. Customization - if these elements were moved to the sql database it
+would allow a simple librarian to determine which fields to display on the page
+without editing any html (also how the fields should behave when being searched).
+
+=back
+
+However, they create one problem : the strings aren't translated. I have an idea
+for how to do this that I will purusue soon.
+
+=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 Koha query - the query that is 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 non-Zebra
+Z39.50 targets to acomplish the field weighting and relevance ranking.
+
+=item 2 Federated query - the query that is passed to other Z39.50 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 Search description - passed to the template / saved for future refinements of
+the query (by user)
+
+This is a simple string that completely expresses the query in a way that can be parsed
+by Koha for future refinements of the query or as a part of a history feature. It differs
+from the human search description:
+
+1. it does not contain commas or = signs
+
+=item 4 Human search description - what the user sees in the search_desc area
+
+This is a simple string nearly identical to the Search description, but more human
+readable. It will contain = signs or commas, 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.
+
+=head3 Additional Notes

+Not yet completed...
