In this paper, we present a flexible architecture to implement a robust information retrieval system based on domain and linguistic modelling by means of a set of conceptual probabilistic and non-probabilistic grammars. It allows certain complexity in the functionality of the application, such as applying non-SQL functions to the results of SQL queries in order to retrieve information not explicitly included in the database, or translating certain natural spoken sentences that would produce difficult embedded queries.
