When using helm-projectile-find-file, if I want to find java file (end by .java). I typed java, but it could also list file of
jav/test/a.a jav/test1/a.a jav/test2/a.a
How to make it work only list the file name whose continuous chars form a "java" word? Also I tried to regular express, such as "java$", but it doesn't work. Any way to support regular express?
