1. A method using digital data processing means and stored textual block identifiers in a table for locating in a stored data base having a plurality of textual blocks, those textual blocks having the best match with a query, the textual blocks in the data base having words grouped into such textual blocks, the textual block identifiers being grouped and each group of textual block identifiers corresponding to one of the blocks in the stored data base, each of the textual block identifiers providing an indication of one of the textual blocks in the stored data base which contains the word corresponding to the group of textual block identifiers in which the textual block identifier is located, the method comprising the steps of: (a) receiving a query having representations of a plurality of query words to be located in the textual blocks contained in the stored data base; (b) determining, for each one of a plurality of the query words, at least one corresponding set of equivalent words which are contained in the stored data base, each of the equivalent words in such set being equivalent to the corresponding query word and corresponding to one of the groups of textual block identifiers; (c) processing the textual block identifiers contained in the groups of textual block identifiers which correspond to the words in the determined sets of equivalent words to thereby form a representation of a score for at least a first of the textual blocks which is represented by said textual block identifiers, the representation of a score representing the total number of said sets of equivalent words which have at least one of said equivalent words in said at least a first of the textual blocks; and (d) utilizing said representation of a score to provide output data pertaining to at least one textual block, for which a representation of a score has been formed.
2. A method according to claim 1 wherein the textual blocks comprise paragraphs and wherein the step of utilizing comprises the step of outputting the paragraphs as the textual blocks.
