Abstract
A method for performing a search of a plurality of documents for similarity to a query word includes retrieving a first document, and determining a number of occurrences of the at least one query word in the first document. Then, a next document is retrieved and a number of occurrences of the at least one query word in the next document is determined. The steps are repeated until each of the plurality of documents have been retrieved, and the number of occurrences of the at least one query word has been determined in each of the plurality of documents. The query word can include a plurality of query words, all of which are searched in each document, in turn, rather than being searched word by word in the whole collection of documents. The documents are then ranked according to the number of occurrences of the query words determined in each document, and a list of documents is produced according to the document ranking.
