Corpus Selection does not Work

[TheMrSheldon]

The Netspeak server ignores the selected Corpus set in a SearchRequest:

netspeak4-application-ngrams/conf/NetspeakService.proto

Lines 15 to 19 in 3ce67d5

	message SearchRequest {
	string query = 1;
	/// The key of the corpus on which the search query will be executed.
	/// This key has to be the key of one of the supported corporas.
	string corpus = 2;

• SearchOptions should probably have a such a corpus field:
  

  netspeak4-application-ngrams/src/netspeak/model/SearchOptions.hpp

  Lines 11 to 20 in 3ce67d5

  	struct SearchOptions {
  	public:
  	uint32_t max_phrase_count;
  	uint64_t max_phrase_frequency;
  	uint32_t phrase_length_min;
  	uint32_t phrase_length_max;
  	uint32_t pruning_high;
  	uint32_t pruning_low;
