Yes, the RadSearchBox does not always search on the correct string. The times I have encountered this is when: * I type a character. * The SearchBox begins to search. * I type another character while the search is still being performed. * The search is not completed within the time for "_requestDelay" which spawns another search. * When the first search is complete the result is shown. The second search result is discarded. See this video for an example: https://drive.google.com/file/d/0B7ow4cKMV4P-bGY3azBWbjVfeTQ/edit?usp=sharing
