Hi, I have a question on a CQL query like

word and and

Is this a valid CQL query? According to the BNF, I think it is, since
"and" is a valid *term*. THe parse tree can be viewed as -

cqlQuery
 scopedClause
  searchClause
   searchTerm
    term
     identifier: (word)
  booleanGroup
   boolean: (and)
  searchClause
   searchTerm
    term: (and)

So does CQL BNF include "and", "or", "prox", "not" in the *Term* node on
purpose so users can search for these words?

Thanks!

David
