+## NAME
+podman\-search - Search a registry for an image
+
+## SYNOPSIS
+**podman search** [*options*] *term*
+
+## DESCRIPTION
+**podman search** searches a registry or a list of registries for a matching image.
+The user can specify which registry to search by prefixing the registry in the search term
+(example **registry.fedoraproject.org/fedora**), default is the registries in the
+**registries.search** table in the config file - **/etc/containers/registries.conf**.
+The default number of results is 25. The number of results can be limited using the **--limit** flag.
+If more than one registry is being searched, the limit will be applied to each registry. The output can be filtered
+using the **--filter** flag. To get all available images in a registry without a specific
+search term, the user can just enter the registry name with a trailing "/" (example **registry.fedoraproject.org/**).
+Note, searching without a search term will only work for registries that implement the v2 API.
+
+**podman [GLOBAL OPTIONS]**
+
+**podman search [GLOBAL OPTIONS]**
+
+**podman search [OPTIONS] TERM**
+
+## OPTIONS
+
+**--authfile**=*path*
+
+Path of the authentication file. Default is ${XDG\_RUNTIME\_DIR}/containers/auth.json (Not available for remote commands)
+
+Note: You can also override the default path of the authentication file by setting the REGISTRY\_AUTH\_FILE
+environment variable. `export REGISTRY_AUTH_FILE=path`
+
+**--filter**, **-f**=*filter*
+
+Filter output based on conditions provided (default [])
+
+Supported filters are:
+
+* stars (int - number of stars the image has)
+* is-automated (boolean - true | false) - is the image automated or not
+* is-official (boolean - true | false) - is the image official or not
+
+**--format**=*format*
+
+Change the output format to a Go template
+
+Valid placeholders for the Go template are listed below:
+
+| **Placeholder** | **Description**              |
+| --------------- | ---------------------------- |
+| .Index          | Registry                     |
+| .Name           | Image name                   |
+| .Descriptions   | Image description            |
+| .Stars          | Star count of image          |
+| .Official       | "[OK]" if image is official  |
+| .Automated      | "[OK]" if image is automated |
+
+**--limit**=*limit*
+
+Limit the number of results
+Note: The results from each registry will be limited to this value.
+Example if limit is 10 and two registries are being searched, the total
+number of results will be 20, 10 from each (if there are at least 10 matches in each).
+The order of the search results is the order in which the API endpoint returns the results.
+
+**--no-trunc**
+
+Do not truncate the output
+
+**--tls-verify**=*true|false*
+
+Require HTTPS and verify certificates when contacting registries (default: true). If explicitly set to true,
+then TLS verification will be used. If set to false, then TLS verification will not be used if needed. If not specified,
+default registries will be searched through (in /etc/containers/registries.conf), and TLS will be skipped if a default
+registry is listed in the insecure registries. (Not available for remote commands)
+
+**--help**, **-h**
+
+Print usage statement
+
