All the flavors of search can be overwhelming. But for enterprises hoping to improve worker efficiency and business processes, it’s vital to understand what the current crop of low-cost, middle and high-end search options can and can’t do.

The free OmniFind Yahoo Edition (designed by IBM to get a foothold in the enterprise search space, with the hope of selling product upgrades and services later) certainly has its limits. But Eric Brierly, CTO at Decision Critical, a company that provides online access to medical training and continuing-education programs for hospitals, nurses and doctors, was able to use it for more than just adding public search capabilities to the company’s website (which is how many entry-level search tools are used). Still, it took some tweaking.

Decision Critical hosts training modules for its customers; each customer has access rights to different modules based on what the customer has licensed or provided. That requires Decision Critical to create and maintain separate Web-based course catalogs for each customer. Brierly has long wanted to simplify the maintenance of course pages and their HTML links to course details, and give clients better keyword searching options. When OmniFind Yahoo came along as a free tool, he decided to see if it might solve his problems.

One key limitation of tools such as OmniFind Yahoo is that they index only HTML pages and common document formats such as Microsoft Word, Excel and PowerPoint documents, and Adobe PDF files. They can’t catalog the contents of databases, ERP systems or other corporate information resources. Brierly extended the free version’s capabilities by creating hyperlinks from the HTML course “start” pages to SQL queries that returned the course details as HTML snippets. Thus, Decision Critical tricked OmniFind Yahoo into indexing its database content. One result: “There are no more broken links, since each link is based on what the search engine actually finds,” Brierly says.
