Parameters

successCallback

Type: IBM.Watson.DeveloperCloud.Services.Discovery.v1DiscoverySuccessCallbackQueryResponse
The success callback.

failCallback

Type: IBM.Watson.DeveloperCloud.Services.Discovery.v1DiscoveryFailCallback
The fail callback.

environmentID

Type: SystemString
The environment identifier.

collectionID

Type: SystemString
The collection identifier.

filter

Type: SystemString
A cacheable query that limits the documents returned to exclude any documents that don't mention the query content. Filter searches are better for metadata type searches and when you are trying to get a sense of concepts in the data set.

query

Type: SystemString
A query search returns all documents in your data set with full enrichments and full text, but with the most relevant documents listed first. Use a query search when you want to find the most relevant search results.

aggregation

Type: SystemString
An aggregation search uses combinations of filters and query search to return an exact answer. Aggregations are useful for building applications, because you can use them to build lists, tables, and time series. For a full list of possible aggregrations, see the Query reference.

count

Type: SystemInt32
Number of documents to return.

_return

Type: SystemString
A comma separated list of the portion of the document hierarchy to return.

offset

Type: SystemInt32
The number of query results to skip at the beginning. For example, if the total number of results that are returned is 10, and the offset is 8, it returns the last two results.

customData (Optional)

Type: System.Collections.GenericDictionaryString, Object
Optional custom data.
