Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`isExact()`	Indicates if an index is an exact match, or should also be post-filtered with a value matcher.
`boolean`	`isInvertible()`	Indicates if an index can be inverted for use with a 'NOT' filter.

- Method Detail
  - isInvertible
```
boolean isInvertible()
```
    Indicates if an index can be inverted for use with a 'NOT' filter. Some types of indexes may not be invertible, such as those which provide false positive matches.
  - isExact
```
boolean isExact()
```
    Indicates if an index is an exact match, or should also be post-filtered with a value matcher. Filters which are not an exact match must always use a value matcher as a post-filter, even if they have an index.
  - merge
```
ColumnIndexCapabilities merge(ColumnIndexCapabilities other)
```
