@brief constructs a query-by-example using a skiplist index
`collection.byExampleSkiplist(index, example)`

Selects all documents from the specified skiplist index that match the
specified example and returns a cursor.

You can use *toArray*, *next*, or *hasNext* to access the
result. The result can be limited using the *skip* and *limit*
operator.

An attribute name of the form *a.b* is interpreted as attribute path,
not as attribute. If you use

*{ a : { c : 1 } }*

as example, then you will find all documents, such that the attribute
*a* contains a document of the form *{c : 1 }*. For example the document

*{ a : { c : 1 }, b : 1 }*

will match, but the document

*{ a : { c : 1, b : 1 } }*

will not.

However, if you use

*{ a.c : 1 }*,

then you will find all documents, which contain a sub-document in *a*
that has an attribute @LIT{c} of value *1*. Both the following documents

*{ a : { c : 1 }, b : 1 }*and

*{ a : { c : 1, b : 1 } }*

will match.
