Description
The MemoryIndex itself should just be a builder that constructs an IndexReader instance. The whole notion of freezing a memory index should be removed.
While we change this we should also clean this class up. There are many methods to add a field, we should just have a single method that accepts a `IndexableField`.
The `keywordTokenStream(...)` method is unused and untested and should be removed and it doesn't belong with the memory index.
The `setSimilarity(...)`, `createSearcher(...)` and `search(...)` methods should be removed, because the MemoryIndex should just be responsible for creating an IndexReader instance.
