Abstract
A method for indexing with redundant information. The method may identify unknown code points for a document in response to an indexing request for the document. The method may further convert the identified unknown code points into a plurality of converted code points. Each set of converted code points of the plurality uses a different codepage. The method may further identify sets of same code points and sets of redundant code points from the plurality of converted code points. The method may build an index based on the sets of same code points and the sets of redundant code points.
