Search by site
When we search for a keyword, on the right side of the search results we get for each entry something like
[PDF] acm.org. This is useful to find the websites you'd like to add.
We can combine these sites:
memory site:ieee.org OR site:acm.org OR site:usenix.org
Search by source
The search results have the name of the conference below the title of each entry. This might be a full title instead of only an acronym and that's what you need to use.
attack source:ASPLOS returns nothing. But we get results using
attack source:"Architectural Support for Programming Languages and Operating Systems".
Using a more broader term for source such as
attack source:"Operating Systems" gives you results for multiple conferences, namely ASPLOS and SOSP because both have operating systems in their name.
