  12 // This script performs client-side searching with the index data file
  13 // (zoom_index.js) generated by the Zoom Search Engine Indexer. It allows you
  14 // to run searches on mediums such as CD-ROMs, or other local data, where a
  15 // web server is not available.
  16 //
  17 // We recommend against using client-side searches for online websites because
  18 // it requires the entire index data file to be downloaded onto the user's
  19 // local machine. This can be very slow for large websites, and our server-side
  20 // search scripts (available for PHP, ASP and CGI) are far better suited for this.
  21 // However, JavaScript is still an option for smaller websites in a limited
  22 // hosting situation (eg: your web host does not support PHP, ASP or CGI).
