You can use the boolean operators and, or, or not in
searching. Without these booleans, the search engine will assume you're
anding the words together.
The operators are case sensitive: use lowercase only. Evaluation takes place from left to right only, although you can use parentheses to force the order of evaluation.
Example: entering "
book or magazine" will retrieve
files containing either the words "book" or "magazine", and
"book and magazine not press" will retrieve
first the files that contain both the words "book" and
"magazine", then among those the ones that do not contain the word
The only wildcard available is * and it can only be used at the end of a word. Usage at the beginning or in the middle of the word will yield no results.
"librarian" only retrieves files
which contain the given word "librarian", but on the other hand
"librarian*" retrieves "librarians",
"librarianship", etc. along with "librarian".
