| | How to Search a WAIS Database |
 | | The WAIS search engine receives a user's question, searches its database for documents most relevant to the question, and returns a relevance-ranked list of documents back to the user. |
 | | In this example, the WAIS Server would search for documents containing the words 'portable' and 'computers'; the other words, 'tell', 'me', and 'about', are called "stop words" -- they are so common that they occur in almost every document, so they are not used for searching a document. |
 | | For this parse format, the WAIS parser detects the "to" and "cc" fields, the "from" and "sender" fields, the "subject" field, and the "date" field. |
