Hello Thank you for you quick responses.
If I disable the index with + it takes around 50% more execution time. I supposed a very fast query even with many records, because COUNT( ) might do its work on the index only. I this case, I have to find another solution to get the number of records quickly. The often discussed "trigger COUNT() solution" might not be applicable here.

Well, if you count almost all records, why do you expect the query to run substantially faster than the one that in fact counts all records?
