PROBLEM TO BE SOLVED: To provide a method and a system of pseudo search, by which a high-precision search result can be obtained using a simple operation in a short time, irrespective of operator's skill level. SOLUTION: A search condition document DB1 stores a search condition document as a search key in a text format. A document DB2 to be searched stores a multiplicity of documents to be searched in a text format. A keyword extracting part 3 extracts a plurality of keywords from the search condition document, stored in the search condition document DB1. A full-text search part 4 implements full-text search, using a keyword extracted by the keyword extracting part 3 as a search key, covering all the documents stored in the document DB2. A pseudo search part 5 implements pseudo search, using the search condition document as a search key covering the results of the full-text search by the full-text search part 4.
