Hello, I'm looking for a solution to match documents from different indexes. Well, I have two indexes, Index 1, contains documents with field message which is a string. Index 2, contains documents with field regex. How Can I apply all the regex in index2 to all the documents in Index1, to find for each string, the most matching regex ? Thank you. ---

You would need to solve that manually. Scroll the index 2 and for each document search in index 1. ---
