Alternatives to boolean search

I would like to get a one-time list of topics that have keyword1 OR keyword2 or keyword3. I have tried similar queries and it looks like Discourse does not yet support boolean operators in the search UI. Are there alternatives (e.g., plugins, Rails tasks) that I could use that could get me the list of topics?

Data Explorer queries immediately come to mind.

Thanks! Ended up using something like this in Data Explorer and it worked great.

SELECT 
  topic_id 
FROM 
  posts 
WHERE 
  raw LIKE '%keyword1%' 
  OR raw LIKE '%keyword2%'
