Claim:
A method, comprising: determining, with a processor, a number of characters to include in a liaoalphagram based on one or more of, an average size of words in a set of correctly spelled words, a mean size of words in the set of correctly spelled words, and a uniqueness measurement that compares uniqueness for tri-liaoalphagrams computed from the set of correctly spelled words to uniqueness for four-liaoalphagrams computed from the set of correctly spelled words; computing a set of liaoalphagrams having the determined number of characters for the set of correctly spelled words, where the set of liaoalphagrams includes at least one liaoalphagram having at least three selectively non-contiguous characters; establishing an inverted index that relates a member of the set of liaoalphagrams to one or more correctly spelled words; and storing the inverted index.
