More information
As Relevanssi indexes the post content, the post content is passed through a multi-step process. First the post content passes through relevanssi_post_content, then more content may be added with relevanssi_content_to_index, then the shortcodes are either expanded or removed, depending on the settings, and then the content passes through this filter hook.
After this filter hook, the invisible elements (<script>, <style>, <embed>, <object>, <applet>, <noscript>, <iframe>, <noembed> and <del> tags) are removed, internal links are processed, and all HTML tags are stripped. After that the content passes through relevanssi_post_content_before_tokenize, then it’s tokenized and passed through relevanssi_indexing_tokens.
If you want to modify the post content somehow, there are many points in the process where to enter. In general relevanssi_post_content is the logical option, but if you specifically want to modify the content generated by a shortcode, this filter hook is the right spot.
