#### 8.1.3 Setting up nnir

To set up nnir you may need to do some prep work. Firstly, you may need to configure the search engines you plan to use. Some of them, like `imap` and `gmane`, need no special configuration. Others, like `namazu` and `swish`, require configuration as described below. Secondly, you need to associate a search engine with a server or a backend.

If you just want to use the `imap` engine to search `nnimap` servers, and the `gmane` engine to search `gmane` then you don't have to do anything. But you might want to read the details of the query language anyway.
