Downloading all the videos for a search result

[Logmytech]

I have a few doubts and questions.

I download youtube search results by using youtube-dl -iltc "https://youtube.com/results?search_query=Pewdiepie" --match-title pewdiepie.
But it downloads only about 20 videos.
What if I want to download all the results even though it may be infinite.

Can I use youtube-dl "ytsearch:pewdipie" for downloading multiple(unlimited) results?

ytsearch<N|all>:pewdipie.

@McSinyx You have to use it like this youtube-dl "ytsearch30:pewdipie" . Without <> or | . This downloads the first 30 videos. I guess if you want all vids for pewdipie search you need youtube-dl "ytsearchall:pwediepie"

All vids with "pewdiepie" included in their title?
That will be a lot. Like really a lot.
