The sentence below seems to me to be correct:

They have the technology that is documented the best.

But, can I use a little bit changed sentence as follow:

They have the technology that is the best documented.

  • "They have the best documented technology" also works.

  • "that is document the best" is not grammatical in English! I'm sorry but I don't understand people saying it is. Not sure the word you want here is documented. They have technology with the best documentation.

  • Their technology is the best documented of all the ones I tried.

  • I'd suggest a hyphen in your version, @MorganFR. "The best documented technology" can be read as "the best technology with documentation" instead of "the technology with the best documentation". The hyphen in "the best-documented technology" guarantees that the adjective applies to the participle. Nov 2, 2016 at 15:01

    "most well-documented" is probably the more common way to say this.

Both of the sentences make perfect sense grammatically, but I think the clearest way to write it would be "They have the best documented technology", as it's more streamlined and less awkwardly worded than the other sentences.

  • No, /that is documented the best/ is simply not grammatical. X has the best documentation. One can use: best documented technology, ok.

  • @Lambie What exactly makes it incorrect? How is it any different from saying "the man who runs the fastest"? Nov 2, 2016 at 15:03
  • I'd say that it may sound kind of awkward, but I don't think there's anything grammatically wrong with it. Nov 2, 2016 at 15:05
  • For me, it is not native speaker of English usage at all. You might say: "They have the technology that is documented the best" but you would not write it.

  • I agree that it's bad writing, but is still doesn't make it grammatically incorrect, just clunky. Nov 2, 2016 at 15:46
