Alan Woodward commented on LUCENE-7394:
---------------------------------------
We'd still need a way to set a Similarity so that we can encode norms, I think?
The tricky part here is going to be untangling the various shared block pools.
We need to make sure that calling .addField() doesn't change the data
referenced by a previously created IndexReader, which is where I got stuck last
time I tried playing around with this idea.
Another nice cleanup would be to remove the global storeOffsets and
storePayloads settings and instead set them per-field.

> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Martijn van Groningen
>
> 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.
