I believe exact match is trying to detect ISBNs among other strings. I was wondering if the functionality may also be extended to look for a DOI pattern, and search matches based on that ? [Cool DOI’s – DataCite Blog](https://blog.datacite.org/cool-dois/)

I think the search could look for patterns with and without the https:// e.g.:

this: [https://doi.org/10.1080/01639374.2017.1388326](https://doi.org/10.1080/01639374.2017.1388326)
