11/// Command for searching Docker Hub repositories
12///
13/// The `SearchCommand` provides a builder pattern for constructing Docker search commands
14/// with various filtering and limiting options.
15///
16/// # Examples
17///
18/// ```rust
19/// use docker_wrapper::SearchCommand;
20///
21/// // Basic search
22/// let search = SearchCommand::new("redis");
23///
24/// // Search with filters and limits
25/// let search = SearchCommand::new("nginx")
26///     .limit(25)
27///     .filter("stars=10")
28///     .no_trunc();
29/// ```
