    Abstract: A data processing method is disclosed for storing and retrieving text. The method achieves a significant level of efficiency in compression over prior art without having to compress the token dictionary through an iterative tokenization of the text and tokens. A benefit of the uncompressed token dictionary is faster searches and decompression of tokenized text. To achieve faster searches, an index with a given text resolution for each unique word is created and added as an additional column element in the alphabetized word table. Since tokens consisting of multiple tokens populate the tokenized text, they are parsed to tokens that represent unique words before a search for a word or phrase is conducted. In a relatively large text such as a Bible, there could be a large number of tokens that consist of multiple tokens, which could take fair amount of time to parse. Therefore, the method includes a step of creating an additional index that is added as an additional column element in the alphabetized word table.
