Hi

I am new to Elasticsearch.

We are planning to a database that has the following columns.

[USER-ID USER-NAME GROUP PARENT-GROUP GROUP-JOIN-DATE]

The database would have billions of entries. An user belonging to a particular group may have multiple parent group. A parent group decides which specific group a user could be part of. For example A user needs to be part of either Student or Employee group to be part CanteenAccount group.

Is there any way we can do the following?

- Index the document using different fields  
For example, To query all groups a user belongs to, To query all group hierarchy of an user, To retrieve  
all users joining after a date

Thanks
