Feature Tag Indexing seems to be incomplete since December 23

[Langlaeufer]

I'm submitting a (bug report/feature request/ support or question)

Brief Description

I have been monitoring several regions for over a year. Since the problems with the Overpass interface at the end of last year, it seems to me that tag indexing is still not working correctly.

What is the motivation / use case for this feature?

Select all recent changes affecting highway in an area

What is the current behaviour, (attach relevant screenshots) ?

incomplete listing - not all edited highways are listed - (when I remove the "OSM feature tag" highway from the filter I get the complete result.

When does this occur ?

since dec. 2023

it is not the spacial index, it's the tag index
Does the meanwhile the way how tags are indexed change?

Example:

Indexing is still not working correctly. No canges of highway indexed since 4 days. This is not correct!
