102  ◾  Software Engineering: The Current Practice

comprehension and concept location are discussed by Rajlich (2009) and by Rajlich

and Wilde (2002).

Searches in an electronic environment have been discussed by Marchionini

(1997). A grep search is described by Petrenko, Rajlich, and Vanciu (2008), and the

original description of the dependency search was provided by Chen and Rajlich

(2000). ese two concept-location techniques, described in this chapter, do not

require any special preprocessing of the code; therefore, they are easy to use, even

when the code is incomplete. ere is a large set of other techniques that do require

code preprocessing; see, for example, information retrieval techniques similar to the

ones that are used to ...
