\description{
\code{KorAPQuery} objetcs represent the current state of a query to a KorAP server.
New \code{KorAPQuery} objects are typically created by the \code{\link{corpusQuery}} method.

q <- fetchAll(corpusQuery(new("KorAPConnection"), "Ameisenplage"))
q@collectedMatches

q <- fetchRest(fetchNext(corpusQuery(new("KorAPConnection"), "Ameisenplage")))
