retroflix API calls return nothing

I attest that there is not an existing issue for this?

• I have searched the existing open and closed issues

I attest this is not related to a Cardigann YML Indexer.

• I confirm this is not related to a Cardigann YML Indexer

Current Behavior

Prowlarr is not able to return any results from retroflix indexer.

Expected Behavior

Prowlarr should be able to query retroflix API

Steps To Reproduce

After short investigation, I discovered that API in fact return only 2 bytes (brackets):

I checked with curl and this is actually the case

curl -H "Authorization: Bearer $TOKEN" 'https://retroflix.club/api/torrent?itemsPerPage=2&sort=torrent.createdAt&direction=desc&search=threads+1984'
[]

After playing around with API examples in https://retroflix.net/api/doc, I found that if I will add &searchIn=title (allowed values are title, description, uploader, imdb), then I'm getting results properly

curl -H "Authorization: Bearer $TOKEN" 'https://retroflix.club/api/torrent?itemsPerPage=2&sort=torrent.createdAt&direction=desc&search=threads+1984&searchIn=title'
[{"download_volume_factor":1,"upload_volume_factor":1,"is_freeleech":false, ... REDACTED

So this seems to me like prowlarr error, as retroflix seems to have its own custom API.

Environment

- OS: Debian Bookworm
- Prowlarr: linuxserver/prowlarr:2.5.2
- Docker Install: yes
- Using Reverse Proxy: yes

What branch are you running?

Master
