Sanne Grinovero commented on HSEARCH-471:
-----------------------------------------

About _IndexingActionTypeonDelete_ use cases, some of the people requesting this issue wanted it primarily for performance reasons. One request is to be able to have the indexing engine not touch the index during peak hours (index will be kept optimized, and take better advantage of FieldCache and filter caches, reusing the same IndexReader); today one can change the ReaderProvider to not refresh itself, being able to disable index changes is better. I had this configuration myself on some systems, the reindex all over the night to recover consistency; Having this is better than avoiding to register the listener as you can control it per entity-type.

Another problem is that because we exclude non indexed fields and don't trigger a Work event in this case, we need to force the user to index all the fields that will possibly involve the soft delete logic even if the field is not meant to be indexed int he first place.

An alternative is to list the fields that ought to force a Work trigger. Ideas?

This is how I think it could work:
OperationType.REMOVE -> We remove, whatever our information on dirtyness: the entity must be "hidden".
OperationType.SKIP -> We avoid creating any work, whatever our information on dirtyness.
OperationType.PASS_THROUGH -> We look at dirtyness (business as usual).
Basically we need to invoke the interceptor before looking at the dirtyness.

> In our system we have entities that are searched but not all of them are available for search - some of them are flagged as "removed".  It would improve the efficiency of our search subsystem if we could implement a kind of "filter" that blocked these entities from being added to the search index, since we wouldn't have to make that a search term and our indexes would be somewhat smaller.
