   I have seen other query engines introduce specialized versions of some expressions to handle this issue. For example, we could use something like this to represent many expressions connected with `or`.
   
   ```rust
   struct Or {
     expr: Vec[Expr]
   }
   ```
   
   We could maybe generalize to:
   
   ```rust
   struct ChainedExpr {
     op: Operator,
     expr: Vec[Expr]
   }
   ```
