is parsed into AST:


(N_SELECT_STATEMENT (N_FROM (N_TABLE_NAME [Table])) (N_SELECT (N_CREATE_COLUMN 
(N_EXPRESSION (N_CALL_PARAMS (N_EXPRESSION (N_COLUMN (N_COLUMN_NAME *))) 
(N_COLUMN (N_COLUMN_NAME COUNT))))) (N_CREATE_COLUMN (N_EXPRESSION (N_COLUMN 
(N_COLUMN_NAME word))))) (N_WHERE (N_EXPRESSION (N_CONTAINS (N_COLUMN 
(N_COLUMN_NAME word)) (N_STRING 'th')))))
