I have the following problem: I have a database containing more than 2 million records.

Each record has a string field X and I want to display a list of records for which field X contains a certain string. To make it more concrete: in the GUI of my application I have a text field where I can enter a string.

Above the text field I have a table displaying the (first N, e.g.

100) records that match the string in the text field.
