Support for special search qualifiers in verdaccio REST API /-/v1/search

[WeiXie96]

Is your feature request related to a problem?
We are trying to use the Verdaccio rest API to search the packages in the registry, and we want to add some search filters, for example, author, maintainer, and keywords. The special search qualifiers are available in the search API of NPM, we are asking if it is possible to also implement it in Verdaccio.

Describe the solution you'd like
Currently the sample search in the REST API is /-/v1/search?text=react&size=20&from=0&quality=0.65&popularity=0.98&maintenance=0.5, we want to filter the packages in verdaccio with batman in keywords with for example /-/v1/search?text=keywords:batman.
