Review Comment:
It's because in a SEARCH operator, we get Structs in the Sarg instead of
ROWs. For example, if you run `query47.q` you'll get the following partial
predicate:
```
SEARCH(ROW($6, $8), Sarg[[1999:INTEGER, 12:INTEGER]:RecordType(INTEGER NOT
NULL EXPR$0, INTEGER NOT NULL EXPR$1), [2001:INTEGER,
1:INTEGER]:RecordType(INTEGER NOT NULL EXPR$0, INTEGER NOT NULL
EXPR$1)]:RecordType(INTEGER NOT NULL EXPR$0, INTEGER NOT NULL EXPR$1))
```
The left operand is of type ROW, however the values inside Sargs are
structs. Earlier with 1.25, those right operands were also of type ROW.
