 Description   

Search result rankings based on AI may have memory consumption issues - see https://wiki.magnolia-cms.com/pages/viewpage.action?spaceKey=ARCHI&title=2019-01-17+Memory+issues+with+user+specific+result+rankings  

Some strategies have been implemented or proposed in order to mitigate them, see

  • MLEARN-5 (e.g. per userrole strategy, rankers cached with LRU eviction policy)
  • MGNLPER-79

However, should those strategies not be sufficient, we could look at non-AI strategies to make results more personal. For instance, a result group like "Recently opened by me" is a very common practice used in JIRA, Confluence, Google Drive etc. It doesn't have to be AI ranked, just a log of ~10 recently opened items for each user.

Until having an alternative, the module should be removed from the dx-core reactor.
