Implement database selection from home page
We discussed this in the past, but don't see an issue on it: we should allow users to select the collection that is being searched in the homepage. At a minimum, we need to allow one to select the following opitions:
- Astronomy
- Physics
- Astronomy & Physics
- Everything
A couple of information systems which have something similar to what we want to do are:
- https://www.semanticscholar.org
- https://www.ncbi.nlm.nih.gov/pubmed
In both cases the selection is done via a dropdown selection, and it sticks around in the search box.
One thing which we'd want to make sure is that if somebody sets his/her preferences to search a particular collection, those settings should be refelected in this selection as well.
We decided not to implement this yet but to collect user feedback and potentially get back to this later after having some more usability input.
