+The main class is :class:`~gensim.similarities.docsim.Similarity`, which builds an index for a given set of documents.
 Once the index is built, you can perform efficient queries like "Tell me how similar is this query document to each
 document in the index?". The result is a vector of numbers as large as the size of the initial set of documents,
 that is, one float for each index document. Alternatively, you can also request only the top-N most

 These are more simple but do not scale as well (they keep the entire index in RAM, no sharding).
