Abstract
The invention provides a system and method for retrieving documents from a collection of documents that match a word search query. A word index is generated for each document in which each entry is an enriched-term string built from the stemmed form of the word to be searched and a separator character followed by the original form of the word to be searched. During a retrieving operation, a search query is processed depending the original form or the stemmed form of a word to be searched. Cross-documents tables are addressed to find documents that match the enriched-term string of the word to be searched.
