How to search for video titles containing key words using – youtube api v3? I need to be able to utilise multiple q values if possible?

I am sending requests to the youtube v3 api with the following url:

const url = `https://www.googleapis.com/youtube/v3/search?key=${process.env.YOUTUBE_API_KEY}&part=snippet&q=foo`;

I am going to change this to use channelId to specify channel as foo is the channel name. I want to also use youtube apis search:list functionality to search for videos within a specific channel that have titles containing key words that, as i understand need to be specified via the q parameter.

Is there a way to provide multiple values for q as I need to search video titles on multiple criteria?
