I need to search for a word in a range in the phrase. Example the following sentence:
The HTML was created in 1991, by Tim Berners-Lee, at CERN (European Council for Nuclear Research) in Switzerland. Initially the HTML was designed to interconnect nearby research institutions, and share documents with ease. In 1992, the library ACPU development of WWW, a network of reach the world, which together with HTML provided the World Wide Web.
Always in this text I'll separate the word that is between library and development into a variable, which in this case is unique and specific ACPU . I will always have the same text, but the word in the range will always be different.
