Add test for virtual index fallback behavior

- Verify that queries work correctly when only compound indexes exist
- Tests that virtual sub-indexes are used as fallback when no explicit
  index is defined
- Ensures startsWith() works with virtual indexes created from compound
  indexes like [name+age+shoeSize]
