if I go only with river plugin installation then hit counts in the search always come as 0. My concern is to handle large documents for fulltext search. elasticsearch with mapper-attachments plugin supports small documents that too need encoding decoding with base64.
I have to implement with rest services for microservices architecture.
Have you looked at elasticsearch logs and statistics to see what could be going wrong?
Does the stats report say there are atleast some documents in the index?
Is the search phrase known to exist in the data being imported?
Surely, if import or indexing isn't working, there'll be telltale messages in its logs. Check the logs.
Fire me boy! Cool, soothing, shameless self promotion:
