--- id: searching_messages sidebar_position: 20 title: Searching Messages --- Searching For Messages Across Channels Message search is built-in to the chat API. You can enable and/or disable the search indexing on a per channel type. The command shown below selects the channels in which John is a member. Next, it searches the messages in those channels for the keyword “'supercalifragilisticexpialidocious'”: ```dart final search = await client.search( Filter.in_('members', ['john']), query: 'supercalifragilisticexpialidocious', paginationParams: PaginationParams( limit: 2, offset: 0 ), ); ``` Pagination works via the standard limit and offset parameters. The first argument, filter, uses a MongoDB style query expression. We do not run MongoDB on the backend, so only a subset of the standard MongoDB filters are supported. Additionally, this endpoint can be used to search for messages that have attachments. ```dart // Search file of type videos final response = await channel.search(messageFilter: Filter.in_('attachments.type', ['video'])); return response; ```
