I'm looking for a simple way to search thru the plaintext/source of hundreds of nodes. I need to find-replace all the color settings for a certain font awesome icon (
fa-check), but can't find any good way to check our source for which pages are using that icon. New Drupal admin here, haven't really done any dev work, so answer that doesn't require installing new modules would be great.
We're using Solr for search, incidentally.
