will be treated the same as

Query type There are two different kinds of query.
Scope of queries
Advanced search features
• Queries for all the words. These look for documents (or chapters, or
titles) that contain all the words you have specified. Documents that
satisfy the query are displayed.
• Queries for some of the words. Just list some terms that are likely to
appear in the documents you are looking for. Documents are
displayed in order of how closely they match the query. When
determining the degree of match,
• the more search terms a document contains, the closer it
matches;
• rare terms are more important than common ones;
• short documents match better than long ones.
Use as many search terms as you like—a whole sentence, or even a whole
paragraph. If you specify only one term, it doesn’t much matter whether
you use an all or a some query, except that in the second case the results
will be sorted by the search term’s frequency of occurrence.
In most collections you can choose different indexes to search. For
example, there might be author or title indexes. Or there might be chapter
or paragraph indexes. Generally, the full matching document is returned
regardless of which index you search.
If documents are books, they will be opened at the appropriate place.
While the above is enough to meet most searching needs, some more
advanced search features are provided. These are activated from the
Preferences page, which is reached by clicking the preferences button at
the top of the page—see Section 2.3 below. After changing your
preferences, do not click your browser’s Back button—that would undo
the changes. Instead, click any of the buttons on the search/browse bar.
