Search in file for exact phrase with special symbols [windows 8.1]

Question

When I search, for example, for 'name.txt' in file content it seems that it finds all files with 'name' and 'txt' in any order.
Windows 7 seems to have options related to this, like 'use natural language' and 'find partial matches'. But I see nothing in windows 8.
Please let me know if it's possible to search for exact phrase with special symbols.
Thanks.

When I search, for example, for 'name.txt' in file content it seems that it finds all files with 'name' and 'txt' in any order.
You need to either use the Search tools or learn the Advanced Query Syntax (AQS) that they imply.  Actually you need to do both because the tools only help with the keyword prefix and not with the following syntax that is required to do the specific
search that you want to do.
So, for example, you knew that you wanted to find  name.txt  only in file (or directory?) names so you would use the  Other Properties > Name  tool  to be sure that your query had that prefix  Name:name.txt  
In fact, that was a surprise for me just now because I thought the default syntax for Name with no other specification would be "contains" (which would be Name:~=name.txt) but apparently it defaults to  Name:~<name.txt  which means
"begins with"  name.txt.  In fact, from an efficiency point of view that is probably a logical default.  But from a usability point of view it is terrible because it means that when users really want  Name:name.txt  to mean either
"contains" or "ends with" they won't have a clue what to do to make those differences.
