+### Field selection
 The _fields_ argument is a comma separated list of field names to include in the results. For example `fields=name,age` results in a _option.fields_ value of `{'name':true,'age':true}`. If no fields are specified then _option.fields_ is null, returning full documents as results.
 
-## Sorting
+### Sorting
 The _sort_ argument is a comma separated list of fields to sort the results by. For example `sort=name,-age` results in a _option.sort_ value of `{'name':1,'age':-1}`. If no sort is specified then _option.sort_ is null and the results are not sorted.

 The _offset_ and _limit_ arguments indicate the subset of the full results to return. By default, the full results are returned. If _limit_ is set and the total count is obtained for the query criteria, pagination links can be generated:

-## A note on embedded documents
+### A note on embedded documents
 Comparisons on embedded documents should use mongo's [dot notation](http://docs.mongodb.org/manual/reference/glossary/#term-dot-notation) instead of express's 'extended' [query parser](https://www.npmjs.com/package/qs). Use `foo.bar=value` instead of `foo[bar]=value`.
 
 Although exact matches are handled for either method, comparisons (such as `foo[bar]!=value`) are not supported because the 'extended' parser expects an equals sign after the nested object reference; if it's not an equals the remainder is discarded.
