Finding relevant search results in sharepoint 2013

Question

I had a 5 word documents Test1, Test 2, test 3, test 4 and test 5 and i had variant, score, geoname and complex variant like the below.
Test 1
Variant : 501
Score : 500
GoeName : 502
Test 2
Variant : 500
Score : 502
GoeName : 501
Test 3
Variant : 502
Score : 501
GoeName : 500
Test 4
Variant : 602
Score : 601 GoeName : 600
Complex variant : 500
Test 5
Variant : 500
Score : 700
GoeName : 701
Complex variant : 600
I uploaded all those files in document library and crawled the documents. when i search for variant : 500 using search box instead of getting Test 2 word document which matches exactly what i typed in the search box it is pulling test 4 document. which has
Complex variant : 500 in it.
How can i get relevant search results??
If i search for variant: 500 i should get Test 2 and Test 5 document. If i search for Complex variant : 500 then i should get Test 4 document.

If you think about it as a string matching process you'd expect to get documents all the documents back as they all contain 'Variant' and '500'. The search engine, from start to finish, would need to understand and honour contextual searching to automatically
pick up on that.
If you want to return those results perfectly then you need to surface them as metadata on the items, add those terms as mapped properties which you can search and refine on then build a custom search page for it.
