In this code, I want to replace only 'is' (not 'is' in 'this') with 'are'. So I have created this code. But in the output 'is' did not get replaced with 'are'. Why is that. Please see output below.

Original file content is as follows
Apache is a modular server. This implies that only the most basic func
+tionality
is included in the core server. is it so ?
Extended features are available through modules which can be loaded in
+to Apache.
 By default, a base set of modules is
included in the server at compile-time. If the server is compiled to u
+se dynamic
ally loaded modules, then modules can be
compiled separately and added at any time using the LoadModule directi
+ve. Otherw
ise, Apache must be recompiled to add or
remove modules. Configuration directives may be included conditional o
+n a presen
ce of a particular module by enclosing
them in an <IfModule> block.

Why am I not getting 'is' replaced by 'are' ?
