Abstract: A search query is performed by providing a first data structure containing information about the correlation between a specific search term attribute and at least one block ID of a block being part of a document, identical blocks having the same block ID; providing a second data structure containing information about the correlation between blocks and documents; processing the search query by searching the first data structure for at least one search term attribute and mapping that to the second data structure to retrieve the desired document or documents. The first data structure is preferably an index, each entry being associated with a specific search term attribute and the second data structure is preferably a list of which block is contained in which document.
