Add optional search return fields

[hevp]

As far as I know it is now not possible to set the return data fields on a search_handle call, for example to get the URL or CHECKSUM field value of the persistent identifier along with the handle itself.

Right now a search only returns a list of handles with no additional information. Is it possible to add this?

Is this an issue specific to the new version of B2HANDLE (1.1.1) or this is a feature that is not provided by the library yet?

This is a feature not provided yet by the library.

I can see the value in this, though we have to consider that Handle searching is a fringe feature. I think we can discuss this as a possible enhancement to investigate after the split of the library (pyhandle/b2handle) has been completed.
