How to specify a particular document to be searched in IBM Watson discovery service

Question

IBM Watson Discovery service

I want to get the set of keywords in a particular document in a collection using discovery service. I tried the below url:

https://watson-api-explorer.mybluemix.net/discovery/api/v1/environments/{environment secret key}/collections/{collection secret key}/query?passages=true&count=10&highlight=true&version=2017-11-07

But, it is fetching from all documents in that collection. How can I specify a particular document to be searched?

Answer 1

It's important to know: The collections can have a lot of documents, so the query will search across all your documents inside your collection that you specified if you won't put a field id inside the query.

According to the IBM Watson Discovery Expert @Anish Mathur you can query for a particular document using a field query.

So something like

enviroment/{id envir}/collections/{id coll}/query?query=id:{document_id}

• See the Official API Reference for query with WDS.
