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

423<h1>Welcome to CodeIgniter<a class="headerlink" href="#welcome-to-codeigniter" title="Permalink to this headline"></a></h1>
424<p>CodeIgniter is an Application Development Framework - a toolkit - for
425people who build web sites using PHP. Its goal is to enable you to
426develop projects much faster than you could if you were writing code
427from scratch, by providing a rich set of libraries for commonly needed
428tasks, as well as a simple interface and logical structure to access
429these libraries. CodeIgniter lets you creatively focus on your project
430by minimizing the amount of code needed for a given task.</p>
431<div class="section" id="who-is-codeigniter-for">
432<h2>Who is CodeIgniter For?<a class="headerlink" href="#who-is-codeigniter-for" title="Permalink to this headline"></a></h2>
433<p>CodeIgniter is right for you if:</p>
434<ul class="simple">
435<li>You want a framework with a small footprint.</li>
436<li>You need exceptional performance.</li>
437<li>You need broad compatibility with standard hosting accounts that run
438a variety of PHP versions and configurations.</li>
439<li>You want a framework that requires nearly zero configuration.</li>
440<li>You want a framework that does not require you to use the command
441line.</li>
442<li>You want a framework that does not require you to adhere to
443restrictive coding rules.</li>
444<li>You are not interested in large-scale monolithic libraries like PEAR.</li>
445<li>You do not want to be forced to learn a templating language (although
446a template parser is optionally available if you desire one).</li>
447<li>You eschew complexity, favoring simple solutions.</li>
448<li>You need clear, thorough documentation.</li>
