South Africa - Indexed records

Diana Coates

I have noticed that records that are already indexed do not come up when a search from general "Search" is done. For example: records in Transvaal Probate Records that come up when searching from within Transvaal Probate Records. Is this because the the indexing has not been fully completed?

I am searching from South Africa, so I wonder if there are some restrictions on searches, by country?
