Modifying Hidden YouTube Source Parameters

The Add Source and Source: ... General pages of the Administration Tool present the parameters with which you can configure the connector for most YouTube setups. More advanced and more rarely used parameters are hidden. You can choose to make one or more of these parameters appear in the Add Source and Source: ... General pages of the Administration Tool so that you can change their default value. Consider changing values of hidden parameters when you encounter issues.

The following list describes the advanced hidden parameters available with YouTube sources. The parameter type (integer, string, etc.) appears between parentheses following the parameter name.

IndexPlaylistItems (Boolean) CES 7.0.8541+ (September 2016)

Whether playlist items are indexed. The default value is true. When set to false, playlist item titles are only displayed in the ytplaylistitemstitle field.

BatchSize (Integer)

Number of items to fetch per request made to the YouTube server. The default value is 30 items. The minimum value is 1 item. A small value forces the connector to make small but frequent queries to YouTube. A larger value leads to larger and less frequent queries.

LastRefreshCushion (Integer)

The time set in minutes to ensure the incremental refresh catches all newly uploaded videos. The default value is 180 minutes.

Note: Since the Google API (YouTube Data API v3) has a latency, add this parameter to set the incremental refresh to look for newly uploaded videos during a wider time interval. Without this parameter, if an incremental refresh runs before an uploaded video is available to be caught (YouTube must finish processing the video), the video would not be indexed.
