For my RH Topic Tags
-extension I would like to add a option in the search to search in the tags of topics.
Should I (a) add a field like "search for author" ("search for tag") or should I (b) take the search-key words and extend search to the tags?
I think (b) is more intuitive to understand for users just searching from the index page for example, while (a) is more precise. What do you think?
regarding (a): Which event is best suited for adding the matched topics to the result set?
reagarding (b): how can I extend the search form? I could not find any events?!
