Description

## Feature Request

**Is your feature request related to a problem? Please describe:**

Normal row indexes are not very suitable for complex and flexible search queries.
Search queries may change the column filter frequently, and the selectivity of those filters may also change depending on the constant value.

**Describe the feature you'd like:**

Instead of a lot of row indexes. An index, which is a collection of single-column inverted indexes, is very suitable for this case.

**Describe alternatives you've considered:**

**Teachability, Documentation, Adoption, Migration Strategy:**

Search engines like ElasticSearch
