Other than bringing up each page of a thread and using the browser’s Find function, is there any way to search within a particular thread?
On the Search page, if you click “Show results as posts” rather than “Show results as threads”, that will take you to the posts containing the search term.
Or if you’re looking for a particular term in a particular thread, you go to the thread and then click on “Show Printable Version”; then you just use the Find function in your browser.
