Tools such as web search engines are currently focused on the exhaustive recovery of information. These tools, although very useful in certain contexts, do not respond to the needs of public information services, which aim to be precise, dealing with requests from the public without overloading them with irrelevant information. Just as when a member of the public telephones his city's helpline he wants a single response to his question, a web tool which tries to emulate this service also needs to be precise, ideally providing only one response. To achieve this objective, in this paper we present a search engine which offers precise information to the public, allowing them to ask questions in the language with which they are most comfortable, without this affecting the quality of the service provided.
