Thanks Jonah
I found that by default the search facility was searching pages and events.
To try to limit my search to events I use this as my search form
<form role="search" method="get" id="searchform" action="”>
Search for:
The hidden field will only search the events, however the results bring back all instances of recurring events. For example, I have an event set to recoccur weekly, so the search results bring back 52 instances of the same thing. Do you know whether it is possible to bring back only the upcoming version?
