CentOS

Hi all,

no matter what I try to enter into the search field, I get a message like this:

The following words in your search query were ignored because they are too common words: php update to 7.0
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards.

I am looking for topics about updating CentOS 7 to PHP version 7.0 and forgive me, I have no idea what to enter into the search box to make it work. I tried several combinations but always got this message or similar ones. I am no native speaker, but until today I never got any problems with search engines

Apparently, it is not supported by phpBB. They suggest using Google instead, as in
