Site Search is a class that can search for HTML documents and image files available within server side directories.
It does not need a database, so it is very easy to implement it.
This class will search in the content of each file within a given directory. You can restrict the search to files with given file name extensions. You can also exclude certain directories that should be skipped during the search.
You can split the search process in different sections of files of your site to save time
You can can either search for text documents (like .htm, .php, .asp, etc.) or images. If you download and install the PowerThumb class, the result pages can present thumbnails of the image files that are found.
