Editing excerpts

Hello,

I am using OceanWP theme and the search element of Header, Footer and Blocks from Elementor. The search results show the excerpts of the posts and I have got a few questions regarding the excerpts:
1. The search results show the ‘Continue Reading’ text at the end of the excerpts. How can I remove this without coding?
2. Is it possible to remove the entire excerpts without coding?
3. How can I enlarge the images in the search results with out coding?
4. The post titles in the search results are in different fonts. Where exactly can I change the font type?
5. The search results are too close to the header, where exactly can I change the pagination? I think I went through all the options in OceanWP’s customise but no luck.

In case coding is a must to sort these problems out, can you please explain where exactly in the child theme do I have to post the codes and what codes do I have to post?

Sorry for the many questions, I am a beginner and I am unable to get my head around these. Any help would be much appreciated.

Thanks very much
