Well, you should have some idea about data volumes. You don't say how big a record is. A traditional method of implementing fast searches is to have a data structure that is a tree or split on parts of the data index. For example if part of a keyword started as an alphabetic character, then you can split the dataset 26 ways depending on the first character. If you have a numeric key, then you can have a ten way split depending on the first character. You could have a tree representation. You can keep all this in memory - just download when the app starts. There are loads of established solutions out there for fast lookup. > The AIR has a SQL local data store.
