Hello All,
I am confused about the meaning of the braces in the query syntax:
what does cat(dog) find?
what does cat(dog)* find?
Or is the following defines queries of the following kind?
(cat) AND (dog) AND (bird) and so on. (i.e, one or more bool combinations)
I think it is the last. But I need someone to confirm this.
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' | '||'
-----------------------------
Thanks once again for all the help!
