Android Application Needed

It's a multiple search engine for finding some materials.
Basicly, Users search some materials, find where they are, then be navigated to selected place.
We can say it has 4 steps for demo;
1- Main screen for search lines (multiple search)
2- List of search results
3- Page for places details
4- Navigation for selected place with Google Maps, Yandex etc.

Important detail about it; can be done multiple search and should be filtered by search. Example; If user is searching hammer and nails together; It has to show places which has both of them.

An example for multiple searching; "I'm searching a place which has 'hammer', 'nails', 'book', 'Wifi'" That means we need 4 lines of searching.
Search results should show the places which has all 4 of them, except one or two or three of others.

On the other hand;
I need an Admin Panel to create database by myself. It can't be Google based data, we'll add all information in it from zero.
Section about places which manually added,

About user interface;
Users should enter mail and password.
It can be Google, Facebook or other options of entrance.
For sign up basic user infornation like; name, surname, e-mail, date of birth, gender needed.
