+BUGS
+search for cs --hidden --no-gitignore --no-ignore 英文 cuts in the middle of a rune
+clicking on file in PDF mode shows the binary not the extracted text
 
 TODO
-search by filename
+search by filename (currently only ranks by it) as addtional OR search
 clean up parser so multiple spaces aren't tokens or flag em to be ignored
-if someone enables the --pdf flag not in terminal mode should spawn background process to extract the text so its pre cached
-if in http mode with --pdf need to pull the extracted text when displaying and possibly a link to raw file
-
+add "raw" link on the http page
