The excerpt class is used to store single result of the query, i.e. the excerpt of the corpus which contains the words which the corpus was queried for.

The excerpt is divided into groups, which contain segments, which the texts in the corpus were divided for. The first group is the left context, the second – the matched query, and the last – the right context.
