+// Search module for phpDocumentor
+//
+// This module is a wrapper around fuse.js that will use a given index and attach itself to a
+// search form and to a search results pane identified by the following data attributes:
+//
+// 1. data-search-form
+// 2. data-search-results
+//
+// The data-search-form is expected to have a single input element of type 'search' that will trigger searching for
+// a series of results, were the data-search-results pane is expected to have a direct UL child that will be populated
+// with rendered results.
+//
+// The search has various stages, upon loading this stage the data-search-form receives the CSS class
+// 'phpdocumentor-search--enabled'; this indicates that JS is allowed and indices are being loaded. It is recommended
+// to hide the form by default and show it when it receives this class to achieve progressive enhancement for this
+// feature.
+//
+// After loading this module, it is expected to load a search index asynchronously, for example:
+//
+//         <script defer src="js/searchIndex.js"></script>
+//
+// In this script the generated index should attach itself to the search module using the `appendIndex` function. By
+// doing it like this the page will continue loading, unhindered by the loading of the search.
+//
+// After the page has fully loaded, and all these deferred indexes loaded, the initialization of the search module will
+// be called and the form will receive the class 'phpdocumentor-search--active', indicating search is ready. At this
+// point, the input field will also have it's 'disabled' attribute removed.
