Hello again, Prefix query in general means some thing like the following where the operator is followed by the operands. AND (a,b) OR (a, AND (b,c))
If I apply this to the following definition, it still is not clear what it will find- AND (a,b) (Query)??? Just thought I would give more detail on what I am having trouble with. Thx again! -----Original Message----- From: Aruna Raghavan [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 27, 2001 2:10 PM To: '[EMAIL PROTECTED]' Subject: another simple question on query syntax Hello, Does any one know what is PrefixQuery '(' Query ')'? in the definition of query syntax Syntax: Query ::= Clause ( [ Conjunction ] Clause ) * Where: Clause ::= [ Modifier ] [ FieldName ':' ] BasicClause Modifier ::= '-' | '+' | '!' | 'NOT' BasicClause ::= ( Term | Phrase | | PrefixQuery '(' Query ')' PrefixQuery ::= Term '*' Term ::= <a-word-or-token-to-match> Phrase ::= '"' Term * '"' Conjunction ::= 'AND' | 'OR' | '||' ----------------------------- It seems to imply the following (dog*)((cat) AND (bird)) but I am not sure what this finds.
