Italian record indexing

Good morning everyone, I'd like to clarify a few things about the indexing of Italian documents:

1. Searching my surname on Familysearch in the Tuscan civil registry, 1804-1874 (https://www.familysearch.org/it/search/ ... on/1932364), which is held in the State Archives of Florence, yields a series of results (no longer visible on FS due to an agreement with the Italian state) but can be found on Antenati. The reverse (i.e., searching on Antenati) does not yield the same results.
2. Similarly, the new "full text" search returns different records than the previous search;
3. Is the list of indexed municipalities or years available, and for what type (births, marriages, deaths, decennial indexes, etc.), especially now that they are being indexed with AI and updates appear almost daily? A list was circulating on Familysearch many years ago, but I can't find an updated one; This is because, still using the previous marital status as an example, the indexing is not complete, and it would be useful to understand which periods or types are already indexed and which are not.

Thanks everyone
