sub-indexes, up to the point where a column (or a column's data part) has only a single sub-index. In that case, the sub-index has a
|

"global" view of all column rows and can directly return all granules of the column (part) with relevant rows (there are at most
|

`LIMIT [N]`-many such granules). In a second step, ClickHouse will load these granules and identify the actually best rows by performing a
|

|

brute-force distance calculation over all rows of the granules. With a small `GRANULARITY` value, each of the sub-indexes returns up to
|
||||
`LIMIT N`-many granules. As a result, more granules need to be loaded and post-filtered. Note that the search accuracy is with both cases
|

equally good, only the processing performance differs. It is generally recommended to use a large `GRANULARITY` for ANN indexes and fall
