When the U.S. General Services Administration looked to upgrade the searching capabilities on its GSA Auctions® website, it could have written a host-based search engine to run on the mainframe system. Instead, GSA opted to use "off-the-shelf" Thunderstone Search Appliances — enabling the implementation of an affordable search solution that reduces system load while providing sophisticated search features expected by today's savvy users.
The GSA Auctions® website (http://www.gsaauctions.gov) empowers people in the general public to bid electronically on excess and/or surplus Federal assets. It supports fully web-enabled auctions that permit registered participants to bid on a single item or multiple items (lots) within specified timeframes.
Auctioned items can include run-of-the-mill office equipment and furniture, as well as more exotic Federal assets such as scientific equipment, heavy machinery, airplanes, vessels, vehicles, etc. The website enables GSA to auction-off and dispose of a widely geographically dispersed inventory of products. Participants can bid on and purchase available assets, without worrying about the actual physical location of any particular item or buyer.
Interested individuals may browse products offered on the auction site, or they can choose to search for items and place bids. With flexible and robust search capabilities powered by the Thunderstone Search Appliance, GSA Auctions® takes advantage of Thunderstone's proven technological expertise in the simultaneous searching of both structured and unstructured data.
Prior to implementing Thunderstone's Appliance-based search solution, things shaped up very differently on the website — in terms of its data access and retrieval functionality. Back-ended by a COBOL application utilizing a cgi interface to the mainframe's web server, the site originally supported a basic full-text search that required parsing the complete database to search each active item.
It seemed appropriate to consider deploying new technology, because the GSA Auctions® site deserved a more feature-rich and less resource-intensive search tool.
Thomas Schaefer serves as Systems Architect and consultant to the General Services Administration. He helps the GSA identify innovative ways to derive optimal value from its Unisys ClearPath Mainframe investment and to maximize the productive use of all related I.T. resources.
According to Schaefer, GSA could have written a host-based search engine to run on the system. But, they figured, "Why reinvent the wheel?" Instead, GSA rapidly deployed several off-the-shelf Thunderstone Search Appliances to affordably implement a state-of-the-art search solution with reduced load on the ClearPath system for each request.
"By using Thunderstone Search Appliances, GSA Auctions® has gained the rich search features users have come to expect from sites like Google. The broader point is that, while there is a move to consider total cost of ownership and migrate applications to the ClearPath environment, not every problem requires developing custom mainframe software. Some problems are better solved by integrating existing components, mainframe or otherwise, into composite systems," Schaefer said.
Thunderstone's DataLoad API, which allows data to be pushed into the Appliance, gets used a lot by the people who administer the GSA Auctions® site. And they appreciate the "plug-and-play" reliability of their Thunderstone Search Appliances -- because every added server brings with it an additional production cost. Who wants to maintain yet another server? "With Thunderstone," Schaefer said, "I haven't logged-on in eight months, and everything keeps running just fine."
GSA continues to work with Thunderstone to further enhance and refine its electronic auction offerings to the public, using the Thunderstone Search Appliance model as its standard. Schaefer explained, "We like the fact that we still have the sophistication of Texis, but in an appliance."
The current search solution for the GSAAuctions.gov site includes two load-balanced Thunderstone Search Appliances (Enterprise Edition) located in a Minnesota production environment. Each Appliance runs active-active. Two additional Thunderstone Search Appliances (one Enterprise Edition and one Small Business Edition) are installed at a GSA facility in Utah, for the purpose of ongoing new application development and testing.
Kevin J. Payne, Director of System Applications at GSA, recalled, "We considered several internal and external search alternatives. Tom [Schaefer] came up with the idea of using a search appliance, which basically meant using either Google or Thunderstone."
"Thunderstone demonstrated a real willingness to make changes that we wanted and to customize their standard appliances to meet our needs. The ability to customize was a big thing. Plus, we really like the way the search engine runs," Payne added.
Customization for the GSAAuctions.gov search enhancement project enabled GSA's Thunderstone Search Appliances to add as many as 50 additional data fields (well beyond the three definable fields that come with the standard Appliance) for auction-item searches based on bid amounts and different geographic locations.
Payne said the procurement process was fast and easy. And he expects other key GSA projects to also have their search capabilities powered by Thunderstone Search Appliances in the months ahead. As an example he cited the GovSales.gov (http://www.govsales.gov) website. Part of the Federal Asset Sales Presidential e-Government (E-GOV) initiative, it will very likely implement its own Thunderstone Search Appliance by Fall 2008.
"These are systems that bring in billions of dollars a year to the U.S. government," noted Payne.
The GSA Auctions® site offers a variety of ways to search for desired items:
The professionals who work at GSA sometimes tend to write in government-spec language that typical users do not use themselves. For instance, what GSA refers to as "vehicles" on their auction site does not correspond to terms that most people use when searching for vehicles. Rather, people look for "cars," "sedans," "autos," "automobiles," "SUVs," etc.
With built-in Metamorph concept-based searching capabilities, the Thunderstone Search Appliances saved GSA hundreds of thousands of dollars in development costs, According to Payne.
