Abstract

Knowing the inner workings of an online or CD-ROM system may help to explain strange results, improve search strategies and aid trouble shooting. Discusses search strategies for Boolean and for statistical search engines; how DIALOG's Boolean system treats blank spaces; default settings for searches; how DIALOG defines words; stop words; automatioc truncation and automatic substitute features
