Ernesto and Hilary.
Thanks for the info.
I was trying to switch views so that my end users knew something was 'happening' whilst the data source was being queried. I'm currently using a section on my repeating table to only show data when a field on the table is equal to my "search field". The only problem was, it was taking a long time to return results.
I'm querying a SQL db. However since posing the question I've discovered that if I can move the db or at least a copy of the information I need 'in house' the problem is pretty obsolete and the results returned are much faster.
