New search demo

Demonstrate the new Genesys search concepts:

Depends on genesys-catalog#167 (closed)

TBD

1. How do we display hits in their relevant groups?
2. How do we apply selected hits to appropriate filters?
3. How much does the client have to know about these structures?

Groups

Server response should list hits in their relevant groups, where group name is a label we pass through i18n:

{
 "search.group.partner": {
   "filters": [ "owner.id" ],
   "key": "id",
   "hits": [ { "id": 121, "shortName": "IITA", "title": "..." }, { } ]
 },
 "search.group.descriptor": {
   "filters": [ "descriptor.id" ],
   "key": "id",
   "hits": [ ... ]
 },
 "search.group.crop": {
   "filters": [ "crop" ],
   "key": "code",
   "hits": [ { "code": "cassava", "title": "Cassava" } ]
}
