You can get information stored in ArangoDB back out using queries, optionally accelerated by indexes, and possibly in result batches
Queries are used to filter documents based on certain criteria, to compute or store new data, as well as to manipulate or delete existing documents. Queries can be as simple as returning individual records, or as complex as traversing graphs or performing joins using many collections. Queries are written in the ArangoDB Query Language, AQL for short.
Cursors are used to iterate over the result of queries, so that you get easily processable batches instead of one big hunk.
Views are another type of index, primarily for full-text search. See ArangoSearch.
