A Boolean Phrase is a
string consisting of literals (keywords to search for), parenthesis,
and the following Boolean operators: AND, OR, NOT, NEAR, FAR and STRIP.
Precedence: NEAR, FAR and STRIP higher than NOT, higher than AND, higher than OR Note: Operators should be in
uppercase. Note: Use double-quotes (") to search for the exact phrase: 'search NEAR(5) "boolean phrase"' Note: NEAR, FAR and STRIP refer to
distance between words. For example: X NEAR(0) Y refers to literals X AND Y with no
words between them. X NEAR(2) Y refers to X AND Y
with at most 2 words between them. X FAR(2) Y refers to X AND Y
with at least 2 words between them. X STRIP(2, 5) Y refers to X AND Y with at least 2 words and at most 5 words between
them Separator
Characters:
When searching for "whole words" or
calculating NEAR, FAR, or STRIP distances, the separator
characters definition can be extended by treating additional characters as
word boundaries. Separator characters settings is in: Settings ->
Special Characters section. Example: Normally the string person@server.com
will not be shown as a result of "person OR
animal" query in "whole word" mode, because the
word is whole person@server.com string.
However, if "@" and "." characters are selected as separators, then
"person", "server"
and "com" are treated as separate
words. |
