Wrap asymmetric search model into SearchModels. Test notes search end-to-end

- Wrap asymmetric search model parameters into AsymmetricSearchModel class
- Create wrapper for all search type models. Put notes search model into it
- Test notes search end-to-end from client API layer to results.
  Use model build on test data
