Hello, I am working on cds invenio for some months now.
We have a regular collection of books on various topics and collections are defined as BOOKS ARTICLES and so on but we have Thematic topics that may relate to both of BOOKS and ARTICLES. For this problem i have added a multiselect element to a document type submission and attached it with logical field 'thematic' having marc tag 990__a (used just for testing) and used collection query as: thematic : CLIMATE_CHANGE, for virtual collection Thematic Topics. this CLIMATE_CHANGE is selected during document type submission. Is there a better way of doing this or this is fine. Also i found that /CLIMATE | BIO/ gave all records from both collections, but /CLIMATE & BIO/ gave nothing (or i did miss something). how do i get records that are only present on both CLIMATE and BIO. I want this thematic topic be on separate box like " Narrow by Collection and Focus On " on WebSearch. How can i do this. I am fine with python so playing with code wouldnot be problem for me. Thank you, Diwaker Kathmandu, Nepal
