      "age"                      GDataYouTubeAge       : Read / Write

Restricts the search to videos uploaded within the specified time period. To retrieve videos irrespective of their age, set the property to `GDATA_YOUTUBE_AGE_ALL_TIME`.

Default value: GDATA_YOUTUBE_AGE_ALL_TIME

Since 0.3.0

### The `"format"` property

      "format"                   GDataYouTubeFormat    : Read / Write

Specifies that videos must be available in a particular video format. Use `GDATA_YOUTUBE_FORMAT_UNKNOWN` to retrieve videos irrespective of their format availability.

Default value: GDATA_YOUTUBE_FORMAT_UNKNOWN

Since 0.3.0

### The `"has-location"` property

      "has-location"             gboolean              : Read / Write

Whether to restrict search results to videos with specific coordinates associated with them. If used with a given "latitude" and "longitude", only videos with specific coordinates (not those with merely a descriptive address) will be returned. If used without a latitude and longitude set, only videos with specific coordinates (regardless of those coordinates) will be returned.

For more information, see the documentation for "latitude".

Default value: FALSE

Since 0.3.0

### The `"language"` property

      "language"                 gchar*                : Read / Write

Restricts the search to videos that have a title, description or keywords in a specified language. The language code should be a two-letter ISO 639-1 code; or you can use `zh-Hans` for simplified Chinese and `zh-Hant` for traditional Chinese.

For more information, see the online documentation.

Default value: NULL

Since 0.3.0

### The `"latitude"` property

      "latitude"                 gdouble               : Read / Write

The latitude of a particular location of which videos should be found. This should be used in conjunction with "longitude"; if either property is outside the valid range, neither will be used. Valid latitudes are between `-90` and `90`0 degrees; any values of this property outside that range will unset the property in the query URI.

If "location-radius" is a non-`0` value, this will define a circle from which videos should be found.

If "has-location" is `TRUE`, only videos which are associated with specific coordinates in the search circle will be returned. Otherwise, videos which have a relevant descriptive address (but no specific coordinates) will also be returned.

For more information, see the online documentation.

Default value: 0

Since 0.3.0

### The `"license"` property

      "license"                  gchar*                : Read / Write

The content license which should be used to filter search results. If set to, for example, `GDATA_YOUTUBE_LICENSE_CC`, only videos which are Creative Commons licensed will be returned in search results. Set this to `NULL` to return videos under any license.

For more information, see the online documentation.

Default value: NULL

Since 0.11.0

### The `"location-radius"` property

      "location-radius"          gdouble               : Read / Write

The radius, in metres, of a circle from within which videos should be returned. The circle is centred on the latitude and longitude given in "latitude" and "longitude".

Set this property to `0` to search for specific coordinates, rather than within a given radius.

For more information, see the documentation for "latitude".

Allowed values: >= 0

Default value: 0

Since 0.3.0

### The `"longitude"` property

      "longitude"                gdouble               : Read / Write

The longitude of a particular location of which videos should be found. This should be used in conjunction with "latitude"; if either property is outside the valid range, neither will be used. Valid longitudes are between `-180` and `180` degrees; any values of this property outside that range will unset the property in the query URI.

For more information, see the documentation for "latitude".

Default value: 0

Since 0.3.0

### The `"order-by"` property

      "order-by"                 gchar*                : Read / Write

Specifies the order of entries in a feed. Supported values are `relevance`, `published`, `viewCount` and `rating`.

Additionally, results most relevant to a specific language can be returned by setting the property to `relevance_lang_`languageCode``, where `languageCode` is an ISO 639-1 language code, as used in "language".

For more information, see the online documentation.

Default value: NULL

Since 0.3.0

### The `"restriction"` property

      "restriction"              gchar*                : Read / Write

The IP address that should be used to filter videos playable only in specific countries. This should be the IP address of the client, if different to the IP address in use by the library. Alternatively, it can be an ISO 3166 two-letter country code.

For more information, see the online documentation.

Default value: NULL

Since 0.3.0

### The `"safe-search"` property

      "safe-search"              GDataYouTubeSafeSearch  : Read / Write

Whether the search results should include restricted content as well as standard content.

For more information, see the online documentation.

Default value: GDATA_YOUTUBE_SAFE_SEARCH_MODERATE
