Hello,
I am using with success searchDocuments using the 8.2 version.
The searchDocuments interface looks like in the attached image.
You map in the documents input the list of documents that you want to search and you map to the searchCriteria/key the name of the field from the document.
Example: - let’s say you have the following document
MyDocument
- FieldA
- FiledB
The list[MyDocuments] will be mapped to the documents input.
searchCriteria/key=FieldA
searchCriteria/value=myValue
searchCriteria/CompareStringAs=(string|numeric|datetime) (I used string)
Hope it helps,
Vlad Turian
