Add `search` option to CLI + atomic_lib

@AlexMikhalev is interested in this

To rephrase I need to be able to query from Rust using atomic_lib, cli is option and is an example of how to use API.

Alex does not necessarily need this feature at the moment.

@AlexMikhalev does need this feature now!

@AlexMikhalev The lib code for building a search URL is added to the latest development.
