What does the “Topic Replied To” selection do?
This attribute refers to whether a thread has any replies from a member other than the person who started the topic. If you select “No” then the only threads that will be included in the search results will be those that do not have replies from a member other than the thread starter. Selecting “Yes” will ensure that only threads that have such replies will be returned in the results. Please note that this is not the same thing as a thread having “0” replies. While many threads with “0” replies may be returned when this option is set to “No”, in this context, a thread is still considered “un-replied to” even if the topic starter has posted to their thread multiple times but no one else has replied.
