In the display settings in the section "Timelines" you can define which channels and other timelines you want to see in the "Channels" widget on the network page and which channels should appear in the menu bar at the top of the page.
Also in the display settings in the section "Channels" you can define all the languages that you want to see in your channels. Here you can select more than one language.
On the contact page you can define the channel frequency for every contact. The options are:
* Default frequency: Posts by this contact are displayed in the "for you" channel if you interact often with this contact or if a post reached some level of interaction.
* Display all posts of this contact: All posts from this contact will appear on the "for you" channel.
* Display only few posts: When a contact creates a lot of posts in a short period, this setting reduces the number of displayed posts in every channel.
* Never display posts: Posts from this contact will never be displayed in any channel.
* Circle: This defines the data source for this channel. By default it is set to the public timeline. There are some predefined values, like the accounts that you follow or the accounts that follow you. Also all of your circles can be selected.
* Include Tags: Comma separated list of tags. A post will be used when it contains any of the listed tags.
* Exclude Tags: Comma separated list of tags. If a post contain any of these tags, then it will not be part of nthis channel.
* Full Text Search: This can be used to include or exclude content, based on the content and some additional keywords. It uses the "boolean mode" operators from MariaDB: https://mariadb.com/kb/en/full-text-index-overview/#in-boolean-mode
* Images, Videos, Audio: When selected, you will see content with the selected media type. This can be combined. If none of these fields are checked, you will see any content, with or without attacked media.
Additional keywords for the full text search
---
Additionally to the search for content, there are additional keywords that can be used in the full text search:
* from - Use "from:nickname" or "from:nickname@domain.tld" to search for posts from a specific author.
* to - Use "from:nickname" or "from:nickname@domain.tld" to search for posts with the given contact as receiver.
* group - Use "from:nickname" or "from:nickname@domain.tld" to search for group post of the given group.
* server - Use "server:hostname" to search for posts from a specific server. In the case of group postings, the search text contains both the hostname of the group server and the author's hostname.
* source - The ActivityPub type of the post source. Use this for example to include or exclude group posts or posts from services (aka bots).
* source:person - The post is created by a regular user account.
* source:organization - The post is created by an organisation.
* source:group - The post is created by or distributed via a group.
* source:service - The posts originates from a service account. This source type is often used to mark bot accounts.
* source:application - The post is created by an application. This is most likely unused in the fediverse for post creation.
* network:dspr - The Diaspora protocol is mainly used by Diaspora itself. Some other systems support the protocol as well like Hubzilla, Socialhome or Ganggo.
* network:feed - RSS/Atom feeds
* network:mail - Mails that had been imported via IMAP.
* network:stat - The OStatus protocol is mainly used by old GNU Social installations.
* network:dscs - Posts that are received by the Discourse connector.
* network:tmbl - Posts that are received by the Tumblr connector.
* network:bsky - Posts that are received by the Bluesky connector.
* platform - Use this to include or exclude some platforms from your channel, e.g. "+platform:friendica". In the case of group postings, the search text contains both the platform of the group server and the author's platform.
So for example you can create a channel with all posts that talk about the Fediverse - that aren't posted in the Fediverse with the search terms: "fediverse -network:apub -network:dfrn"
