Indexing

We have optimized the database indexing, and as a result, system efficiency has improved by 50%.

I read the article "Indexing Exoplanets with Physical Conditions Potentially Suitable for Rock-Dependent Extremophiles."

The system was devised for cataloguing and indexing purposes, but it was found on trial to be equally valuable for numbering and arranging books and pamphlets on the shelves.

In zero-based indexing, array variables in a computer program are numbered upwards from zero.
