I don't think that this response is correct. The documentation for the
index types can be found on the oak site: property index:
https://jackrabbit.apache.org/oak/docs/query/property-index.htmllucene
index: https://jackrabbit.apache.org/oak/docs/query/lucene.html The huge
difference is that property indexes are synchronous, but lucene indexes
are async. When you work with custom indexes, you should use Lucene
indexes.
