Exclude specific keywords from Blogspot RSS feed

I've posted before about taking more advantage of Blogger's provided RSS feeds to help you get content at a more granular level. But real quick, I wanted to show a good way of following Blogger blogs via RSS that gives you a nice level of filtering of posts. 

We can use common AND, OR, NOT syntax in Blogger searches, and turns out they can apply to RSS feeds too. 

Usually, I have a set of keyword terms that I know I am not interested in at all. Usually politics stuff. But whatever your case, try this:

First, use the normal Blogger search to sift out posts you don't want using syntax like this:

https://sample.blogspot.com/search?by-date=true&q=-term1+-term2+-term3+-term4 

Once you're satisfied, turn it into an RSS feed pretty simply [UPDATE: fixed a dumb typo; thank you to Panda Mery for pointing it out]:

https://sample.blogspot.com/feeds/posts/default?by-date=true&q=-term1+-term2+-term3+-term4

We add the ?by-date=true argument because otherwise, the results come back just like a normal Blogger search would return them: by relevancy. But if you're following via RSS, we can safely assume you want recency, not relevancy. 

Use this trick to help filter the junk from a Blogspot blog.

HT to Too Clever By Half for this idea.
