NOT operator for filter queries

[Gorka Egino Arroyo]

Hi,

According to the documentation,

> Simple logic operators can also be used in filters:
> filter=type:(wav OR aiff) filter=description:(piano AND note)

But I couldn't get the NOT operator working. I tried this:

https://freesound.org/apiv2/search/text/?filter=tag:(NOT guitar)

And I got an empty response:

HTTP 200 OK Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept { "count": 0, "previous": null, "next": null, "results": [] }

Is there something I am missing? Or could the NOT operator be implemented for filters? (I am aware that you can do that in the query text, but I am looking specifically to using it with filters)

hi!

Thanks for bringing that up. Negative operator is implemented with "-" sign, but I just realized there is a bug that does not allow to use it. You can use it if you do something like that filter=tag:(-guitar piano), but you can't use it "alone".

I hope that helps,

frederic

gràcies Frederic!
Maybe the API Docs (on resources > search resources > text search > the 'filter' parameter > " Simple logic operators can also be used in filters:...") could be updated to reflect this possibility?

Also, is there any plan to fix the bug for using the negative operator 'alone'?
