Adding Newznab Indexers
Indexers function as the search engines of Usenet. When searching for a missing comic, CLU queries your configured Newznab indexers for releases matching the wanted series and issue, then passes the matching .nzb release directly to your download client.
Indexers are configured in the Download Clients tab in Settings.

Indexer Fields
| Field | Description |
|---|---|
| Name | A recognizable label for the indexer (e.g. Drunkenslug, Geek, NinjaCentral). |
| URL | The full base API URL for your indexer (e.g. https://api.indexer.com). |
| API Key | Your personal API key provided in your indexer account profile. |
| Category | The Newznab category ID to query. Defaults to standard comic category 7030. |
| Priority | Sets query precedence when multiple indexers are enabled (see below). |
Comics Category ID
Newznab-compliant indexers universally standardize comic books under category ID 7030 (Books > Comics). Only alter this value if your specific indexer utilizes a custom non-standard categorization schema.
Indexer Priority Ordering
When configuring multiple indexers, Priority determines the sequence in which indexers are queried and displayed:
- Higher-priority indexers are searched first.
- Results from higher-priority indexers are displayed first in manual search modals and automated queues.
Indexer priority is internal to your Usenet configuration. It works in conjunction with global Source Priority, which decides whether Usenet as a whole is queried before or after GetComics and DC++.
Search Visibility
Usenet results remain hidden in manual search modals and automated sweeps until at least one indexer has been configured and enabled with a valid API key.
