Ignores the skipping indexes specified if used by the query.
Consider the following example:
```sql
CREATE TABLE data
(
key Int,
x Int,
y Int,
INDEX x_idx x TYPE minmax GRANULARITY 1,
INDEX y_idx y TYPE minmax GRANULARITY 1,
INDEX xy_idx (x,y) TYPE minmax GRANULARITY 1

INSERT INTO data VALUES (1, 2, 3);
SELECT * FROM data;
SELECT * FROM data SETTINGS ignore_data_skipping_indices=''; -- query will produce CANNOT_PARSE_TEXT error.
SELECT * FROM data SETTINGS ignore_data_skipping_indices='x_idx'; -- Ok.
SELECT * FROM data SETTINGS ignore_data_skipping_indices='na_idx'; -- Ok.
SELECT * FROM data WHERE x = 1 AND y = 1 SETTINGS ignore_data_skipping_indices='xy_idx',force_data_skipping_indices='xy_idx' ; -- query will produce INDEX_NOT_USED error, since xy_idx is explictly ignored.
SELECT * FROM data WHERE x = 1 AND y = 2 SETTINGS ignore_data_skipping_indices='xy_idx';
```
The query without ignoring any indexes:
```sql
EXPLAIN indexes = 1 SELECT * FROM data WHERE x = 1 AND y = 2;
Expression ((Projection + Before ORDER BY))
Filter (WHERE)
ReadFromMergeTree (default.data)
Indexes:
PrimaryKey
Condition: true

Granules: 1/1
Skip
Name: x_idx
Description: minmax GRANULARITY 1

Description: minmax GRANULARITY 1
Parts: 0/0
Granules: 0/0
Skip
Name: xy_idx
Description: minmax GRANULARITY 1
Parts: 0/0
Granules: 0/0
```
Ignoring the `xy_idx` index:
```sql
EXPLAIN indexes = 1 SELECT * FROM data WHERE x = 1 AND y = 2 SETTINGS ignore_data_skipping_indices='xy_idx';
Expression ((Projection + Before ORDER BY))
Filter (WHERE)

Also you can use [Tuple](/docs/en/sql-reference/data-types/tuple.md) to work around NULL skipping behavior. The a `Tuple` that contains only a `NULL` value is not `NULL`, so the aggregate functions won't skip that row because of that `NULL` value.
