The search engine that people care about seems to be Google Scholar.  They
say you need meta tags at least for authors, title, and date, and it'll
find the abstract in the HTML text:

https://scholar.google.com/intl/us/scholar/inclusion.html#indexing

If the abstract is short, you could put in in the description
meta-tag, but long descriptions are likely to be ignored as SEO spam.
