Thanks Tanya! We've tried to do as you said, but the result is the same...

We want to get all the documents in one index with "coordenadasDestino" != NULL ... in all our documents this field exists but sometime its NULL or doens't have values

If we do:

```
{"constant_score":{"filter":{"exists":{"field":"coordenadasDestino"}}}}*

```

We get all the documents including also the ones who hasn't values for field coordenadasDestino (NULL)

How can we do this?

Thanks in advance! Regards.
