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.
                Thanks once again for all the help!
