In this paper a new approach for achieving the conceptual matching between user queries and web documents is presented. The key of the proposed system is to use FIS-CRM (Fuzzy Interrelations and Synonymy Concept Representation Model) to represent the indexed web pages. This model (also implemented in the FISS metasearcher) is supported by a fuzzy synonymy dictionary and various thematic fuzzy ontologies of terms.
