Medical Search Engine Reviews: WebMD and OMNI

OMNI is especially useful for finding reputable sites (e.g. government agencies, nonprofit organizations, journal articles, research projects, etc.) that can be used to get an overview of a subject. In a search that I did entering the keyword cloning some of the eight documents I retrieved were from the sites of the Center for Bioethics at the University of Pennsylvania (US), Human Genetics Advisory Commission (UK), AIDS reagent project (UK), and the Society, Religion and Technology Project (Scotland).

Search Tips

In OMNI's Simple Search mode, you can use quotation marks to indicate a phrase and the Boolean operators AND and OR .

The Advanced Search mode allows you to choose additional search parameters and lets you specify how you want your results to appear on the page. For example, there are menu choices for searching only specific types of resources (e.g. reports, position statements, news services, etc.). And you can select use truncation, in order to search for other endings of your search words (e.g., the search word invest will retrieve investment, investor, investing, etc.)

Results

Each result in OMNI includes the title, an extremely comprehensive description of the site, and links to related keywords that the item is indexed under. Selecting one of these keywords provides a list of websites about that topic.
