Those two values are used to specify the analyzer type you want. That can be of two kinds, one for the indexer- the analyzer you specify analyzes the input documents accordingly to build the index. The other one is for query, it analyzes your query. Typically the specified analyzer for index and query are same so that you can search over exactly the token you created while indexing. But you are free to provide any customized analyzer according to your need.
