Special characters
The search engine handles a number of characters in particular ways as described in
the following table:
Characters
, ( ) [
= > < !
' @ ' < { [ !
A backslash (\) removes special meaning from whatever character follows it. To enter
a literal backslash in a query, use two in succession; for example:
<FREETEXT>("\"Hello\", said Packard.")
"backslash (\\)"

Composing search expressions

The following rules apply to the composition of search expressions.
Precedence rules
Expressions are read from left to right. The AND operator takes precedence over the
OR operator. However, terms enclosed in parentheses are evaluated first. When the
search engine encounters nested parentheses, it starts with the innermost term.
Prefix and infix notation
You use can using prefix notation or infix notation to define search strings that use
any operator other than an evidence operator. As a result, either of the following
expressions is valid:
Description
These characters end a text token.
These characters also end a text token. They are terminated by an
associated end character.
These characters signify the start of a delimited token. They are
terminated by an associated end character.
AND (a,b)
This is prefix notation
a AND b
This is infix notation
