Edit: I mean re-publish folders and assets

Sorry, I meant re-publish a large number of nodes (folders and asset).

I need to update all the nodes massively under a specific path in the Assets section of Adobe Media Library.The quick publication option doesn't allow it.Is it possible to rely on the CRX? Can I use an OOB Adobe API?

Currently trying to handle it following @EstebanBustamante's suggestions. Will keep the community posted. 

Is there a way to update the metadata LastReplicationDate of an asset through API or the CRX on AEM?

Yes, case sensitive search works.Nothing is messed up, simply my data on dc:description are not only lower case writtenThat's not a solution since I need my data as they are written Thank you anyway.

Need to try the solution with custom properties but no out of the box solution found.

Don't see AEM 6.5

Edited my response: I misunderstood what you were saying.

No, I didn't
