Add native support of our indexing protocol
As the last step on our joint project with the INRIA, the main idea is to natively support our indexing protocol proposal directly in our store.
It means to validate the possibility for blox/applications/the search engine to come with their declarative configuration in the form of Shapes (existing vocabulary to define constraints on data models and vocabularies) that the store can interpret to figure out possible search requests.
This needs to be investigated as part of NGI Search too.
