- Domino® Query Language
  Domino® Query Language (DQL) is a facility running on a Domino server that provides a terse, shorthand syntax for finding documents. It supports a wide variety and complexity of search terms. It leverages existing design elements, avoiding the need to write detailed code to access them. DQL consolidates all methods in Domino for searching document contents.
- Composite Applications - Design and Management
  Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.

      Extracts a specified number of the rightmost characters in a string.
    - RightB function (LotusScript® Language)
      LotusScript® Release 3 and later use Unicode, a character set encoding scheme that represents each character as bytes. This means that a character can be accompanied by leading or trailing zeroes, so HCL no longer recommends using RightB to work with bytes.
