<p>A method of enabling a user to obtain at least a predetermined number of different responses, that is a threshold value (T, UT), to a query (Q) sent in a data network (100) is provided. The method comprises receiving a query (Q), which query (Q) comprises a query information (QE) and a threshold value (T) and optionally previously obtained responses (PR). Responses to the query (Q) are obtained at entities (1; Peer B, Peer C) in the data network (100), and an updated query (UQ) is propagated in the network (100). The updated query (UQ) comprises an updated threshold value (UT) being decreased by the number of new different responses found at the entity (1) sending the updated query (UQ), and identification of query responses obtained at the entity sending the updated query and of the query responses being identified in the query sent to this entity. The updated query (UQ) may be performed at further entities until the threshold value is decreased to zero and the predetermined number of different responses thus has been received by the requesting entity (9).</p> |
