ElasticSearch custom indexer

Junior Member Posts: 25 Join Date: 3/14/19 Recent Posts
Hi everyone, 

We managed to use indexers for our custom entities in our Service Builder, but we wanted to edit the "doGetDocument" method from User indexer, in order to get specific fields from search hits.

What is the best method to do so ? We tried a custom indexer, extending from BaseIndexer<User> but it is not implemented or called while reindexing.

Do we need to create a hook ? Is there any way to search a user and have specific JSON in hits ?

Thanks !

You define an implementation of IndexPostProcessor. They will attach to an existing instance and is used to modify what that indexer does.
