Thomas Mueller commented on OAK-8971:
-------------------------------------
So the advantage of using valueRegex is that it can greatly reduce the size of
the index, if most values don't contain "%%".
> Indexing: dynamic boost, as an alternative to IndexFieldProvider

> Project: Jackrabbit Oak

>
> The org.apache.jackrabbit.oak.plugins.index.lucene.spi.IndexFieldProvider is
> a callback that allows to change the behavior of indexing. There are multiple
> problems:
> * (1) Not available using oak-run
> * (2) Only available for Lucene indexes
> Instead of a callback, a configuration option in the index property should be
> added, such that the most commonly used features are available in oak-run,
> and can be implemented in other indexes (e.g. Elastisearch, Solr).
