   Hello - I have a custom wordpress website and our news page contains a list of all our 'posts' by way of teaser text (approx the first 20 words).

   Some of these posts contain images with captions - however the caption code appears in the teaser text on the main news page!

   I have spent several hours trying to find a way to remove these - but none seem to work.

   The closest I got was

   add_filter('the_content', 'strip_shortcodes');
   
   function remove_shortcode_from_index($content) {
     if ( is_search() ) {
       $content = strip_shortcodes( $content );
     }
     return $content;
   }

   But this only works on the posts, not on the main news index. And even then it removes the entire image rather than just the caption.

   Use the_excerpt() on the page - not the_content().

   We don't want to have to manually write excerpts each time if possible - there are thousands of posts and this adds an extra time consuming step

   You don't have to. the_excerpt creates an automatic excerpt. If you want to reduce the default excerpt output from 55 words to 20, use something like:

   // Decrease excerpt length
   function my_excerpt_length($length) {
   	return 20; // Or whatever you want the length to be.
   }
   add_filter('excerpt_length', 'my_excerpt_length');

   Another new handy function which might help in similar situation wp_trim_words()
