[EP-tech] Re: Adding fields to admin search

- Just seen Gilles reply - read that first - it's more concise! I'd already typed most of this - sending it for reference!

I'm glad I put that '3.3.10' caveat in my reply :o)
It works wonderfully for that version.

For 3.3.12, I'm basing this on the GitHub repo.
1. Same screen: https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Screen/Staff/EPrintSearch.pm
2. Entirely different to 3.3.10.
3. Looks like it redirects the search to .../cgi/search/eprint/staff
4. Look at cgi/search https://github.com/eprints/eprints/blob/3.3/cgi/search 
5. This splits the incoming part to make 'eprint' the $datasetid, and 'staff' to be the $searchid.
6. The searching is then done by https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Screen/Search.pm
7. Which in turn calls 'search_config' from the dataset: https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/DataSet.pm
8. Eventually ending up at this line: 
	$repo->config( "search", $searchid );
9. And searching the code/GitHub: https://github.com/eprints/eprints/blob/3.3/lib/cfg.d/eprint_search_staff.pl - make note of the comments at the top!
10. Someone write it all up for the Wiki :o)

Cheers,
John

Hi John,

We¹re on 3.3.12 here - I¹ve tried what you suggested to no avail. To be
honest, I¹m not sure where you¹re getting the search config information
from; I¹m following you up til point 4 okay but I don¹t see anything in
that file to indicate what config to use :/
