Query expansion biobank search TODOs

DONE :

• Partly added configuration variable for controlling query expansion option (use of ontologies) . 
• UI (.ftl file) adjusted to show ontology options according to configuration.
  • Yes, I would like to keep the query expansion using ontologies (which indeed need to be locally copied).
  • - But please do add a configuration option that disables the feature in the plug-in constructor
  • - Then people don't have to fiddle with the OWL/OBO files if they don't like it
  • - And complete your 'search' plugin with a little manual that explains what you need to do to get it running (so either disabling the query expansion or downloading the necessary files).

• Will we need a ppt 4 hackathon ?
• if yes --> changes pages of indexing adding new features as porter stemmer ...etc
