The best place to learn about types of variables and variable-related
syntax and behaviour in general is the core cookbook:
http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.1.x
This also describes many matching operations, operators for
prepending, etc.
More sophisticated string operations, such as selection of substrings,
regular expression matching, component extraction, splitting into
tokens by a delimeter, etc. are known as "transformations." They can
be applied to most variables, and an examination of them is found here:
http://www.kamailio.org/dokuwiki/doku.php/transformations:3.1.x
If the question is more about which variables are defined/exposed in
certain situations, the pseudovariables doc is most appropriate:
