You can also utilize the power of the Linux / GNU Commands, by installing "Git for Windows" from https://www.git-scm.com/download/win ( accept its default recommendations, while setup ) and then :
Open File Manager & navigate to your search Folder & Right Click on an empty space, to choose "Open Git Bash here"
Copy the below mentioned command and paste it in the "MINGW..:Your_Search_Folder_Path" window and press Enter / Return key to run it. That's it.
find . -type f -name "1-*"
If the results shown by the above command are satisfactory, then I usually follow it up, with the below command, which changes the "Date Modified" value, to the current time, thereby making those files, raise to the top, on the file manager ( when sorted by "Date Modified" descending ) :
find . -type f -name "1-*" -exec touch -m {} \;

Many useful variations of the find and grep commands, for searching files, are given in the links below :
