@litvinovg this is working in Vitro, but not in VIVO. For me it is working for VIVO only if I add

<str name="modTime">${individual.modTime?xml}</str>

into

https://github.com/vivo-project/VIVO/blob/main/webapp/src/main/webapp/templates/freemarker/body/search/search-xmlResults.ftl

The code looks good to me.

How does this relate to the existing timestamp and etag fields? I wonder if there is a way to have the timestamp field updated only when the etag signature field value changes, so that reindexes don't show up as new modifications.

[litvinovg]

Etag and timestamp are only implemented in Solr. From what I know Elastic Search doesn't currently have similar functionality. I think we can switch to using implementation specific realizations once we have it supported by ES and Solr.
