Revise and update Search engines, Solr and Elastic pages:

• In Search Engines, spotlight the comparison between search engines, emphasize that Legacy SE is not intended in production (double-check with Eng/PM)
  • Verify which product editions search engines are available from and update accordingly (Elastic is no longer limited to Experience?)
• In Solr:
  • Change introduction to refer to capabilities, not package history
• In both Solr andElastic:
  • To consider: split page into overview, installation and configuration?
  • Adapt writing style to our guidelines
