 =elfeed-summary-width= regulates the width of the remaining summary window in this case. It is useful because the data in the search buffer is generally wider than in the summary buffer. The variable can also be set to =nil= to disable this behavior.
 ** Other options
 Also take a look at =M-x customize-group elfeed-summary= for the rest of available options.

-** Usage with RSS-bridge
-[[https://github.com/RSS-Bridge/rss-bridge][RSS-Bridge]] is a popular project to generate feeds, which unfortunately generates URLs like =<instance-of-rss-bridge>?action=...=

-Which I don't know how to filter in elfeed, because filtering with ~=~ does not seem to account for the URL params. To resolve this, I've configured nginx the following way:
-
-#+begin_src conf
-location /rss-bridge/ {
-        proxy_http_version 1.1;
-        proxy_set_header Connection "";
-        rewrite ^/rss-bridge/rewrite/([0-9]+)/(.*)$ /$2 break;
-        proxy_pass http://localhost:8085/;
-}
-#+end_src
-
-This allows using URLs like: =<my-rss-bridge>/rewrite/1234/?action...=. Just don't forget the trailing slash.
 
 Setting a unique URL for every feed resolves the problem.
