There are mainly three steps to make an offline search engine for CD-ROM/DVD.
For offline/local/CD/DVD distribution, this URL should be the relative path from where the search
script will be.
By default, if the search engine files will be placed in the root folder (which you have selected in this window), use "./" (which refers to the current directory)
as your base URL.

If all your documents are to be copied to a subfolder names "data" on the CD, and the search engine files are to be copied in the root folder of CD, then you should use "./data/" as the base URL. The "./" refers to the current
directory, and "./data/" means the search engine will find documents in a subfolder "data" of current directory.

If all your documents are to be copied to a subfolder names "data" on the CD, and the search engine files will be copied to a subfolder names "search", you should use "../data/"
as the base URL. The "../" refers to the parent directory, and "../data/" means the search engine will find documents in a subfolder "data" of it's parent directory.

Copy the generated search engine files to the appropriate folder.
