# 3.5 Complex Queries

Catering to a wide range of databases, Inery provides a rich set of complex queries to retrieve documents satisfying particular conditions. Using Inery’s robust query mechanism for complex searches to filter the search as per particular conditions, a user can retrieve the necessary information.

Whilst providing CRUD functionality, it allows for all common queries (Advanced Filter/Sort, Select, Parameter, Summary, AutoLookup, and Action Queries) and provides the ability for creating and manipulating non-relational databases. This facilitates flexibility, since the developer using Inery can implement its usage and create a logic that uses its features to create a relational database structure.
