There was a problem during the migration to Search 6, and the processor for the annotation @IndexedEmbedded apparently does not correctly intepret @IndexedEmbedded() as "no depth defined".

As a result, {{@IndexedEmbedded(includePaths =

)}} will not set the depth to 0 as it should, but to Integer.MAX_VALUE (the default defined on the @IndexedEmbedded.depth() attribute) and will end up incorrectly including the whole embedded document.

The code to change is this (in org.hibernate.search.annotations.IndexedEmbedded):

         Integer cleanedUpMaxDepth = annotation.depth();
         if ( cleanedUpMaxDepth.equals( -1 ) ) {
            cleanedUpMaxDepth = null;
         }

It should be instead:

         Integer cleanedUpMaxDepth = annotation.depth();
         if ( cleanedUpMaxDepth.equals( Integer.MAX_VALUE ) ) {
            cleanedUpMaxDepth = null;
         }
