    For instance, many characters in a font may use the same character width, which would be represented only once in the TFM format, and this value would be referenced by each character, since the index would be significantly smaller than the full-precision numerical value. In the PL format, however, the full value is written out each time it appears.

    Conceptually, an index is simply a mapping between a value and one or more locations. With a functional index, the value stored in the index is the output of the function specified when the index is created. This capability expands what is sargable beyond base column expressions. Sargable operators: =, >, <, >=, <=, BETWEEN, LIKE, IS [NOT] NULL, IN

TeX3.0 was released on March 15, 1990. [12 ...
