Look at multifields.  They let you send the field once and analyze it
multiple times. You also might want to use keyword ananlyzer and lowercase
filter rather than not_analyzed. Folks are used to case insensitivity.

Is there a way to do exact and full text searches without having to create
two different fields?

The documentation (
http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_finding_exact_values.html)
states fields must have the mapping "not_analyzed" in order to avoid
tokenization. This allows exact searches to be done.

In my case, I would like both full text search and exact searches. For
example:

When searching for book titles, a user can input either:

I like ElasticSearch

-OR-

exact="I like ElasticSearch"

The first case will return results from a full text search.

The second case will return results only if the book title is exactly "I
like ElasticSearch". Case sensitivity does not matter.

To do this, I think I will have to create two fields called "book_title"
and "book_title_exact" where "book_title_exact" will have a field mapping
"not_analyzed" so that I can do exact matches.

Is this the proper way of handling my use case? Or is there a simpler way
in ES without having to store a title twice?
