I have documents that have fields such as

```auto
vulns.something_1.a
vulns.something_1.b

```

- the element `something_1` may change between documents
- some documents have the `vulns` entries, and some do not.

My problem: I would like to filter the documents with `vulns.*` fields.

I thought that simply filtering for `vulns.*` would work - it does not. I also trued to use `_exists: vulns.*` - still nothing.

Is it possible to filter documents for those with a filed with a name partially dynamic?

Hello @Wpq,

Did you try something like this?

`vulns* : *`

This query will retrieve all documents `*` from fields starting with `vulns`.

Hope it helps!

Oh thank you! It works. This is the one combination that I dd not try (retroactively, it is indeed obvious)
