If you are facing any problem regarding Entropy Search not returning the expected results then refer the below steps :
Ask your hosting provider to add the php extensions to the list of searchable files in :
root@server[#] vi /usr/local/cpanel/bin/makeindex
then seach for the keyword @EXTS=
replace : my @EXTS= qw(txt html shtml htm); with my @EXTS=qw(“php”,”php3″,”txt”,”html”,”shtml”,”htm”);
save and quit.
Then from CPanel rebuild the Search index from CPanel >> Software/Services >> CGI Center >> Rebuild Search Index
That’s all you are done.
Note : The file should be chattr +i to prevent the cpanel updates to replace it , remove chattr before making the changes.
