I have to fetch the values from different documents in Elasticsearch.
Ex. documents like
BOOKS, AUTHORS, SALES
Books contains values like (id, name, pagecount, type, price, category... etc)
Authors like (id, name, age, address, city... etc)
Sales like (id, bookid, authorid, price, quantity, date... etc)
All 3 under same index group. If I wants to fetch the data from all 3 documents based on matched unique values like id, bookid ad authorid.
I am expecting result all document values with matching data.
Ex: Book name, Author name, Price, Quantity, Date... etc.
Can someone help me to achieve this.
