When using eZ Recommendation's legacy search engine, certain search plugin calls are not proxied to real search (such as ezfind).

Steps to reproduce:

• Install ezrecommendation and enable it's legacy search engine according to docs.
• install ezfind, index contents. (optional: keep solr output open in console foreground)
• hide a content, verify that it is not sent to solr for indexing.

It seems the following methods are missing, which affect indexing on other circumstances such as updating object section, states, node swaping, etc:

• updateNodeSection
• updateObjectsSection
• updateNodeVisibility
• removeNodeAssignment
• removeNodes
• updateObjectState
• swapNode
