::::{dropdown} Prevent LIMIT + MV_EXPAND before remote ENRICH
31
-
Queries using LIMIT followed by MV_EXPAND before a remote ENRICH can produce incorrect results due to distributed execution semantics.
32
-
These queries are now unsupported and produce an error. Example:
33
-
34
-
```yaml
35
-
FROM *:events | SORT @timestamp | LIMIT 2 | MV_EXPAND ip | ENRICH _remote:clientip_policy ON ip
25

stack: ga 9.0.8

```
37

To avoid this error, reorder your query, for example by moving ENRICH earlier in the pipeline.
