Originally developed at San Diego State University, the ht://Dig software
is open source and consists of several different programs:
- ht://Dig: a gathering program that "digs" through your Web site and
creates an index of terms
- htsearch: used to actually search the index created by ht://Dig
- htnotify: notifies you when your pages are out of date.
These programs offer many features to help Web publishers manage their
sites. Using ht://Dig, publishers can:
- Customize search form and search results pages -- Web publishers can include
custom headers, footers and navigation on their results page.
- Index only files actually linked from other Web pages -- unlike the freeWAIS
software used previously, ht://Dig only indexes pages that are linked from other
Web pages. You can upload content pages to your Web site and not worry about ht://Dig
finding them unless you link to them.
- Index pages on multiple servers -- if your site is on more than one server,
ht://Dig can create a single searchable index for content on multiple servers.
- Support custom tuning of search results -- perhaps the biggest challenge with
search tools is getting the most relevant results listed first. ht://Dig lets
you tune the relevancy of your search results in many different ways. For example,
you can increase the relevancy of pages that have the search term in a heading
tag through the ht://Dig configuration file.
- Build and rebuild search indexes easily -- to create a search index for your
site, fill out the request
form (requires UT EID) and an ITS Web consultant will contact you to walk
you through the process of using ht://Dig and create an initial index for your
site. All indexes are automatically rebuilt weekly.
- Include or exclude certain sections of the site in the search -- from one
index you can limit the search results to certain directories so you don't have
to maintain different indexes.
