The advanced search is a very useful and necessary function for every modern search engine. This will enable the user to easily, conveniently combined query types. For example: http://yandex.ru/search/advanced (by YandexSearch) https://www.google.com/advanced_search (be Google)

Steps to reproduce: Please consider incorporating this feature in Yioop. It is highly desirable that Yioop has combined the advanced search all types of queries.

The new tools section of Yioop would be a good place to put a link to advance search. This will be added in the next version

Version 7 of Yioop now has more advanced search options under the hamburger menu,.
