YouTube feeds generator search syntax

You can use + (plus) and | (pipe or vertical bar) for advanced search.

If you wish to generate YouTube feed with videos which mention several keywords in title and description use + operator.
Example: cats+dogs (and cats and dogs)

Or you can simply use a space when you enter your keywords.
Example: cats dogs (and cats and dogs)

If you wish to combine searches into one single feed then you use | operator.
Example: cats|dogs (or cats or dogs)
