partial search term does not provide document search results

Hello there

As a client of ours noticed, the following search term does not provide the document below in the screenshot within the search results:

Is there a way to optimize such search terms within M-Files to deliver partial results? Wildcard characters, as is known, cannot be applied before the search term.

There are a lot of settings within the advanced Vault setting, which do not seem to influence this behavior:

We're using IDOL Search Engine, I tested it with DT Search as well, DT search does not provide the document either.

Maybe some of you guys have experience with this, our client is not too happy with this limitation (even explorer search would provide the document with this search term). Many thanks in advance for sharing.
