1. A method comprising:

  • receiving, at a receiving node, a query from an originating node in a distributed network, the query including an original quality threshold;

    identifying at least one result satisfying the query;

    determining a response delay for a response to the query based on a response plan for the query and a quality for the at least one result, wherein the response plan defines different response delays based on different qualities of query results;

    generating the response to the query including the at least one result;

    sending the response after the response delay has expired;

    receiving, at the receiving node, a re-issued version of the query from the originating node having a lower quality threshold that is less than the original quality threshold;

    identifying at least one result satisfying the re-issued version of the query and having a quality greater than or equal to the lower threshold and less than the original quality threshold;

    determining a response delay for a response to the re-issued version of the query based on a response plan for the re-issued version of the query and a quality for the at least one result satisfying the re-issued version of the query;

    generating the response to the re-issued version of the query including the at least one result satisfying the re-issued version of the query; and

    sending the response to the re-issued version of the query after the response delay for the response to the re-issued version of the query has expired.
