Metadata search interface

By steingod |

The metadata search is now implemented and working. Currently only some products from the Norwegian Meteorological Institute are listed, but we are now harvesting metadata from the the other nodes and testing the quality control and ingestion. This will continue for the next weeks. The current implementation will be updated early 2018. The main fixes in the enxt release will be better utilisation of facets from the search engine. Furthermore, the current version is checking the content of OPeNDAP datasets while searching, this will be moved to a preprocessor step in the next version. This will speed up the search.
