Relevant Search: With Applications for Solr and Elasticsearch

For more in depth reading about search, ranking and generally everything you could ever want to know about how lucene, elasticsearch or solr work under the hood I highly suggest this book. Easily one of the most interesting technical books I have read in a long time. If you are tasked with solving search relevance problems even if not in Solr or Elasticsearch it should be your first reference. Amazon Affiliate Link

472<p>The <code class="docutils literal"><span class="pre">$config</span></code> array contains your configuration variables. It is passed to
473the <code class="docutils literal"><span class="pre">$this-&gt;pagination-&gt;initialize()</span></code> method as shown above. Although
474there are some twenty items you can configure, at minimum you need the
475three shown. Here is a description of what those items represent:</p>
476<ul class="simple">
477<li><strong>base_url</strong> This is the full URL to the controller class/function
478containing your pagination. In the example above, it is pointing to a
479controller called “Test” and a function called “page”. Keep in mind
480that you can <a class="reference internal" href="../general/routing.html"><span class="doc">re-route your URI</span></a> if you
481need a different structure.</li>
482<li><strong>total_rows</strong> This number represents the total rows in the result
483set you are creating pagination for. Typically this number will be
484the total rows that your database query returned.</li>
485<li><strong>per_page</strong> The number of items you intend to show per page. In the
486above example, you would be showing 20 items per page.</li>
487</ul>
488<p>The <code class="docutils literal"><span class="pre">create_links()</span></code> method returns an empty string when there is no
489pagination to show.</p>
490</div>
491<div class="section" id="setting-preferences-in-a-config-file">
492<h3><a class="toc-backref" href="#id3">Setting preferences in a config file</a><a class="headerlink" href="#setting-preferences-in-a-config-file" title="Permalink to this headline"></a></h3>
493<p>If you prefer not to set preferences using the above method, you can
494instead put them into a config file. Simply create a new file called
495pagination.php, add the <code class="docutils literal"><span class="pre">$config</span></code> array in that file. Then save the file
496in <em>application/config/pagination.php</em> and it will be used automatically.
497You will NOT need to use <code class="docutils literal"><span class="pre">$this-&gt;pagination-&gt;initialize()</span></code> if you save
498your preferences in a config file.</p>

503<p>The following is a list of all the preferences you can pass to the
504initialization function to tailor the display.</p>
505<p><strong>$config[‘uri_segment’] = 3;</strong></p>
506<p>The pagination function automatically determines which segment of your
507URI contains the page number. If you need something different you can
508specify it.</p>
509<p><strong>$config[‘num_links’] = 2;</strong></p>
510<p>The number of “digit” links you would like before and after the selected
511page number. For example, the number 2 will place two digits on either
512side, as in the example links at the very top of this page.</p>
513<p><strong>$config[‘use_page_numbers’] = TRUE;</strong></p>
514<p>By default, the URI segment will use the starting index for the items
515you are paginating. If you prefer to show the the actual page number,
516set this to TRUE.</p>
517<p><strong>$config[‘page_query_string’] = TRUE;</strong></p>
518<p>By default, the pagination library assume you are using <a class="reference internal" href="../general/urls.html"><span class="doc">URI
519Segments</span></a>, and constructs your links something
520like:</p>
521<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">test</span><span class="o">/</span><span class="nx">page</span><span class="o">/</span><span class="mi">20</span>
522</pre></div>
523</div>
524<p>If you have <code class="docutils literal"><span class="pre">$config['enable_query_strings']</span></code> set to TRUE your links
525will automatically be re-written using Query Strings. This option can
526also be explicitly set. Using <code class="docutils literal"><span class="pre">$config['page_query_string']</span></code> set to TRUE,
527the pagination link will become:</p>
528<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">test</span><span class="o">&amp;</span><span class="nx">m</span><span class="o">=</span><span class="nx">page</span><span class="o">&amp;</span><span class="nx">per_page</span><span class="o">=</span><span class="mi">20</span>
529</pre></div>
530</div>
531<p>Note that “per_page” is the default query string passed, however can be
532configured using <code class="docutils literal"><span class="pre">$config['query_string_segment']</span> <span class="pre">=</span> <span class="pre">'your_string'</span></code></p>
533<p><strong>$config[‘reuse_query_string’] = FALSE;</strong></p>
534<p>By default your Query String arguments (nothing to do with other
535query string options) will be ignored. Setting this config to
536TRUE will add existing query string arguments back into the
537URL after the URI segment and before the suffix.:</p>
538<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">test</span><span class="o">/</span><span class="nx">page</span><span class="o">/</span><span class="mi">20</span><span class="o">?</span><span class="nx">query</span><span class="o">=</span><span class="nx">search</span><span class="o">%</span><span class="nx">term</span>
539</pre></div>
540</div>
541<p>This helps you mix together normal <a class="reference internal" href="../general/urls.html"><span class="doc">URI Segments</span></a>
542as well as query string arguments, which until 3.0 was not possible.</p>
543<p><strong>$config[‘prefix’] = ‘’;</strong></p>
544<p>A custom prefix added to the path. The prefix value will be right before
545the offset segment.</p>
546<p><strong>$config[‘suffix’] = ‘’;</strong></p>
547<p>A custom suffix added to the path. The suffix value will be right after
548the offset segment.</p>
549<p><strong>$config[‘use_global_url_suffix’] = FALSE;</strong></p>
550<p>When set to TRUE, it will <strong>override</strong> the <code class="docutils literal"><span class="pre">$config['suffix']</span></code> value and
551instead set it to the one that you have in <code class="docutils literal"><span class="pre">$config['url_suffix']</span></code> in
552your <strong>application/config/config.php</strong> file.</p>
