Description:
------------
In the website search box, I enter a value, such as PHP_SELF, I then chose "online documentation".  After pressing the -->, I get a new screen with the message "Internal Error, Try Again Later.  I've attempted this search process for several weeks (?since late July) with different search value, all with the same results.  (Early in July, I had great success with several different search values.)

There are other similar bug reports, but the problem persists. Rather than searching through the "online documentation" in multiple languages, it would be helpful to just search through the manual in one language.

Expected result:
----------------
The "Internal Error" message go away.  I can search the online documentation.
