- introduce the "base rank" concept. All SearchIndexablesProvider will have a base rank and the Settings one will get a "0" base rank. - use a map whose key is the authority name for the provider to get and store the base rank - if a base rank is not defined, use the current max defined one and increment it to define the new one. Then we will compute the real rank this way: rank = (providerRank > 0) ? baseRank + providerRank : baseRank Change-Id: Ifa82bfcdfc07f25c4a5f304f47550686f7d4c13d
