Document retrieval by information unit
A method of searching a search space comprising a plurality of pages in response to a query comprising a plurality of keywords includes identifying at least one information unit. Where a query includes exactly two keywords, an information unit comprises one page which contains both keywords in the query or two pages selected from the search space such that the first page in the information unit contains the first keyword in the query and the second page in the information unit contains the second keyword in the query; where an information unit contains two pages, one page is linked, directly or indirectly, to the other page. Relaxed query processing techniques enable the method to identify information units which do not contain every keyword in the query, which have only semantically similar words or synonyms, and which have keywords of differing relative importance. The method is adapted to report the identified information units and to accommodate altered queries provided as a result of a report.
