A text is encoded as a file in electronic memory for reading and search
purposes. A lexicon-file is established in which each term that can
searched is incorporated. A text-file is established in which non-search
terms are directly encoded and in which all of the search terms (that is
all of the terms in the lexicon-file) are designated by linking numbers.
The linking numbers link through each incidence of the lexicon word as a
text word and finally link back to the same lexicon word in the
lexicon-file and then from the lexicon-file back to the text-file. In this
fashion, by using numbers to link through each incidence of a lexicon word
in the text-file and the encoded lexicon word in the lexicon-file, the
word is encoded in memory only once and all other entries for the word are
in terms of linking numbers.
