I'm trying to enhance a working filter I wrote that does the first `dissect` with only attempting that from now on if field `source` contains _audit.log_ or using a different `dissect` if `source` contains _debug.log_. Then, if either succeeds, I'd like to remove the `message` field (that I will have parsed using `dissect`).

```
  if "audit.log" in [source]
  {
    dissect
    {
      mapping =>
      {
        "message" => ...
      }
    }
  }
  else if "debug.log" in [source]
  {
    dissect
    {
      mapping =>
      {
        "message" => ...
      }
    }
  }
  if "_dissectfailure" not in [tags]
  {
    remove_field => ["message"]
  }

```

(Yes, the ellipses cover real, working code.) As I say, when this code wasn't surrounded by the `if then else if` conditional, it worked.
