Search Filters fix:
- make them work for static filters (e.g datasource pages)
- make it work when new filter is substring of selected filter (e.g 'Registry' & 'Registry of repositories')
- make it work with and without quotes
SEO:
- datasource landing add description in meta tags
- result landing make h2 the title in other versions (only one H1 per page)
