Thanks for your reply, if I manage to solve it I will post the solution, but I'm stuck on that FSCrawler and Logstash stores the data differently. I made another post about it: Logstash escaping characters, want to disable - Elastic Stack / Logstash - Discuss the Elastic Stack
The result is I can't match with the enrich/ingest/pipeline.
This is the difference:
Logstash JDBC plugin "path": "\"\\publicerat\\IN0010.pdf\"",
FSCrawler: "virtual": """\publicerat\IN0010.pdf""",
