 Yep supports Open Graph and some JSON-LD at the moment. A look through the source code for Alexandria and Gigablast didn't seem to reveal the use of any structured data. The surprising quality of results from SeSe and Right Dao seems influenced by the crawlers' high-quality starting locations (e.g. Wikipedia).

 : Although it's a Chinese engine, its index seems to have a large-enough proportion of English content to fit here. The engine is open-source; see the [SeSe back-end Python code](https://github.com/RimoChan/sese-engine) and [the SeSe-ui Vue-based front-end](https://github.com/YunYouJun/sese-engine-ui). It has surprisingly good results for such a low-budget project. Each result is annotated with detailed ranking metadata such as keyword relevance and backlink weight. Discovered in my access logs.
