Ah, thanks. I've set this up (using ES python bindings):
es.indices.put_mapping(index="myindex",
doc_type="books",
body={
"books": {
"properties": {
"title": {
"type": "string",
"fields": {
"name": { "type"
: "string" },
"raw": { "type":
"string", "index": "not_analyzed" }
} } } } } )
Then I try to search for exact match:
es.search(index='myindex', doc_type="books", body={"query": { "filtered": {
"filter": { "term": { "title": { "raw" : "I like Elasticsearch" } } } } } }
)
But I get an ES error stating
nested: QueryParsingException[[myindex] [term] filter does not support
[raw]]; }]')
It seems like I'm not searching for the raw correctly. How would I specify
to search for the raw title (exact matching)?

Is there a way to do exact and full text searches without having to create
two different fields?
The documentation (
Elasticsearch Platform — Find real-time answers at scale | Elastic)
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?
