First, this search engine provides you with the means to search three of the primary fields in the database, e.g., the keywords, the tip contributor, or a description of the tip. Note that the delimiter for searching in these fields is that that the data must "contain" what you type in any of these three fields. Only fields that contain data will be returned. In other words, if a teacher did not submit references with her tip, then no references will be returned in the found set or record.

Second, choose the number of records to be returned in the found set. If you choose 10, then only 10 records will be displayed in the found set.
