@brief counts the number of documents cursor.count()

The count operator counts the number of document in the result set and returns that number. The count operator ignores any limits and returns the total number of documents found.

Note: Not all simple queries support counting. In this case null is returned.

cursor.count(true)

If the result set was limited by the limit operator or documents were skiped using the skip operator, the count operator with argument true will use the number of elements in the final result set - after applying limit and skip.

Note: Not all simple queries support counting. In this case null is returned.

@EXAMPLES

Ignore any limit:

@EXAMPLE_ARANGOSH_OUTPUT{cursorCount} ~ db._create("five"); ~ db.five.save({ name : "one" }); ~ db.five.save({ name : "two" }); ~ db.five.save({ name : "three" }); ~ db.five.save({ name : "four" }); ~ db.five.save({ name : "five" }); db.five.all().limit(2).count(); ~ db._drop("five") @END_EXAMPLE_ARANGOSH_OUTPUT

Counting any limit or skip:

@EXAMPLE_ARANGOSH_OUTPUT{cursorCountLimit} ~ db._create("five"); ~ db.five.save({ name : "one" }); ~ db.five.save({ name : "two" }); ~ db.five.save({ name : "three" }); ~ db.five.save({ name : "four" }); ~ db.five.save({ name : "five" }); db.five.all().limit(2).count(true); ~ db._drop("five") @END_EXAMPLE_ARANGOSH_OUTPUT
