Introduction
htdig is a webpage search engine licensed under the GNU Public License. It uses a very simple configuration file to allow it to search only the webpages you specify. For example, you can exclude the cgi-bin or a testing directory from the search engine. In addition to installing it on a webserver, some programs use it as a search engine plugin such as Glade, the GTK+ User Interface Builder. In addition, it will create a searchable database of any website. You just supply to URL.

Configuring htdig
Once you have htdig installed, you must make a few changes to the configuration file and the HTML templates into which the search results are embedded.
HTML Templates
If you don’t want to use the default look-and-feel of htdig, you can edit the following files to use the look-and-feel of your website. The paths may be different if you choose to change the paths of them in your configuration file.

Configuring htdig
Once you have htdig installed, you must make a few changes to the configuration file and the HTML templates into which the search results are embedded.
Configuration File
The configuration file for htdig is located at/opt/www/htdig/conf/htdig.conf.
It is pretty self-explanitory. The main attributes you need to
configure are as follows. It will work if you leave the defaults for
the other options or change them if you wish.| Attribute | Value | Example |
| start_url | URL of your site | http://www.mywebsite.com |
| exclude_urls | Directories you do not want searched separated by white spaces | /cgi-bin/ /testing/ |
| adminstrator | Email address of administrator | admin@mywebsite.com |
| search_results_header | HTML file to be used as header of search results. Only use this if
you don’t want to use the default location for the header file: /opt/www/htdig/common/header.html |
/home/httpd/search/header.html |
| search_results_footer | HTML file to be used as footer of search results. Only use this if
you don’t want to use the default location for the header file: /opt/www/htdig/common/footer.html |
/home/httpd/search/footer.html |
| nothing_found_file | HTML file to be displayed if there is no match to search string
entered. Only use this if you don’t want to use the default location
for the header file: /opt/www/htdig/common/nomatch.html |
/home/httpd/search/nomatch.html |
| syntax_error_file | HTML file to be displayed if there is a syntax error in the search
string entered. Only use this if you don’t want to use the default
location for the header file: /opt/www/htdig/common/syntax.html |
/home/httpd/search/syntax.html |
If you don’t want to use the default look-and-feel of htdig, you can edit the following files to use the look-and-feel of your website. The paths may be different if you choose to change the paths of them in your configuration file.
/opt/www/htdig/common/header.html/opt/www/htdig/common/footer.html/opt/www/htdig/common/nomatch.html/opt/www/htdig/common/syntax.html
- Next, you must setup the search database by running the script
/opt/www/htdig/bin/rundig. - Copy the default
search.htmland images from/opt/www/htdocs/htdigto a directory namedhtdigoff of your webRoot. If the images are not in this directory, they will not appear unless you configure it otherwise ithtdig.conf. - Copy
/opt/www/cgi-bin/htsearchto thecgi-binfor your webserver. - Test the search engine by opening
search.htmlin your browser and entering a search string. - Because the search engine uses a database to return results, the database must be rebuilt with the
rundigcommand used in step 1 every time any pages are added to the website. - If you want to configure anything else, refer the the htdig website. Pretty much everything is configurable with htdig.
