Message Search

Search messages across channels using full-text search or specific field filters. Enable or disable search indexing per channel type in the Stream Dashboard.

Searching Messages

Search requires a channel filter and either a text query or message filter conditions.

using System.Text.Json;

var resp = await chat.SearchAsync(new
{
    payload = JsonSerializer.Serialize(new
    {
        filter_conditions = new Dictionary<string, object>
        {
            ["members"] = new Dictionary<string, object> { ["$in"] = new[] { "john" } }
        },
        query = "supercalifragilisticexpialidocious",
        limit = 10
    })
});

Sorting

Results are sorted by relevance by default, with message ID as a tiebreaker. If your query does not use $q or $autocomplete, all results are equally relevant.

Sort by any filterable field, including custom fields. Numeric custom fields are sorted numerically; string fields are sorted lexicographically.

Pagination

Two pagination methods are available:

Offset pagination allows access to up to 1,000 results. Results are sorted by relevance and message ID. You cannot use custom sorting with offset pagination.

Cursor pagination (using next/previous) allows access to all matching results with custom sorting. The response includes next and previous cursors to navigate between pages.
