Overwrite last_modified with another metadata

(from github.com/arengore)
I’m indexing several msg email files, I want to overwrite file last_modified with email date, so i picked the field “Last-Save-Date” calling it dmodified:

crawler.metadata.name.mapping=\
title=title:string\n\
Title=title:string\n\
Last-Save-Date=dmodified:string\n\

query.additional.response.fields=dmodified
query.additional.search.fields=dmodified

The field is picked by crawler and I can see it on ES.
On crawler Config Parameters I entered
doc.last_modified=doc.dmodified

but last_modified don’t change it’s value.

Where I’m wrong?

(from github.com/marevol)

doc.last_modified=doc.dmodified

? The above setting does not exist…

It may work if Last-Save-Date is ISO 8601 format and replacing dmodified with last_modified.

no way, the metadata are ingested from elasticsearch and then becomes unmodifiable.

So, I’m using a bash script to change files timestamp.

Hello,

I have seen you commit #2019, I have tested it with msg file and also with pdfs.

With msg the Last-Save-Date wins over file timestamp, but with pdf the winning is always file timestamp.

Shouldn’t be Last-Save-Date be winning always if present?

I attach a sample pdf with timestamp winning.

It’s not for PDF.
