I recently started using usenet, still learning how it works. I read a few articles and decided to go with Eweka as a provider and Nzbgeek and Nzb.su indexers. Then I found that bundled with Eweka comes the NewsLazer app that has multiple cool features like browsing groups and downloading / generating previews... The problem is, that I am searching for content in my language and there is not much of it. So instead of searching things I like, sometimes I would like to check what is available. NewsLazer seems to be only aware of a few languages (and has some other issues). Is there another tool capable of the same but maybe with additional customisation?
From what I understood you are trying to get access to international languages media.
Omicron's newzlazer, like easynews search, is useful because it can deobfuscate some stuff that you can't find manually in some indexers, but if you are looking for international content, what will matter for you are what indexers you have access. Here are some options:
Search for "Non-Mainstream Movies Statistics in Usenet Indexers" at german google should find you a analysis comparing availability of hundreds of releases separated in about 30 languages (it is a handmade study, not some crazy prowlarr stats).
Oh, thank you!
