Many video hosting services allow users to add tags when uploading a video. For example, a new video about DataSift might include this set of tags:
"DataSift, big data, new feature, Twitter"
This target is populated for videos but not for comments on videos.
Filter for videos tagged with "Lady Gaga":
video.tags contains_any "Lady Gaga, ladygaga"
Filter for videos tagged "iPad" or belonging to a category that includes the word "mobile". Not all video sites include tags so you cannot guarantee that they will be present. When you filter against video.tags, you might choose to include a logical OR command:
video.tags contains "iPad" or video.category contains "mobile"
Target service: Video
Always exists: No
