// This script performs client-side searching with the index data file
// (zoom_index.js) generated by the Zoom Search Engine Indexer. It allows you
// to run searches on mediums such as CD-ROMs, or other local data, where a
// web server is not available.
//
// We recommend against using client-side searches for online websites because
// it requires the entire index data file to be downloaded onto the user's
// local machine. This can be very slow for large websites, and our server-side
// search scripts (available for PHP, ASP and CGI) are far better suited for this.
// However, JavaScript is still an option for smaller websites in a limited
// hosting situation (eg: your web host does not support PHP, ASP or CGI).
