However, the interactive search page does not enable or document all of the features provided by the search engine.

Because the search index is word-based, other punctuation is largely ignored. A search request may have several arguments, including query, searchorder, searchmax, searchthesaurus, and searchwv.

Since spaces are not allowed in URLs, spaces in the query string should be replaced with plus signs. The query argument corresponds to the text box requesting key words on the interactive search form.
