Databases:
Britannica.com now includes four major databases:
Strengths:
Weaknesses: Default Operation: Multiple search terms are processed as an OR operation by default. Boolean Searching:: Full Boolean searching is supported for AND, OR, and NOT. Operators must be in upper case. Scripted Boolean searches are available from the advanced search. The default operator is currently an OR. The + and - operators can be used instead of AND or OR. Proximity Searching: ADJ is available and specifies that the two terms must within 15 characters of each other in the specified order. The ADJ operators must be in upper case. Double quotes can be used, but they force an ADJ operation rather than a true phrase search. The "exact phrase" option in the advanced search is also the ADJ operator and not a true phrase search. Truncation: According to its help file, Britannica supports truncation with the asterisk * symbol. However, it does not work in practice, as of Nov. 14, 1999. Search terms do still are automatically searched as a stemmed search. In other words, the results include all forms of the term including plural, singular, and tense. Case Sensitivity: Britannica has case sensitive searching. Lower case search terms will retrieve any case or mixture of cases. For an exact case match, use at least on upper case letter in a search term.
Field Searching: In the advanced search, a title search is available.
Stop Words: Britannica does have stop words and even publishes its stop word list. Sorting: The sites appear to be sorted by relevance.
