The search mechanism uses a "stemming" mechanism to find words which are similar to the words you enter. For example, a search on


may turn up articles containing similar words such as transcript and transcribed. These additional words may not always be highlighted in the text. If you wish to disable stemming, enclose each individual term in quotation marks. If you do so, and also use Boolean connectors to combine terms, be sure that AND, OR, or NOT are not included in the quotation marks.
