I am using the following guide (link: http://atlas.incubator.apache.org/InstallationSteps.html) for building and installing Atlas.
In the guide the user needs to create three collections in Solr, vertex_index, edge_index and fulltext_index. I would like to know what is the purpose of these and how do they work in order to index?
Also, how does indexing work in Atlas?
Thanking you in anticipation.
