XData $filter "like"

TXDataClient
Is there a filter like "SQL: like"? (or begins with, end with, contains, not contains)
Or, what ist the best way in a searchmask to search a name in a table with up to 1 million datasets?

I want show first results, if the user types some letters.

Thanks, Thomas

I forgot: I use XData with Aurelius
