What's the right way to do an OR search in Discourse?

Data Explorer is the only way at the moment.

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?
