I'm putting together a proposal for a website and one of the things that we're providing is a knowledge base for users to find solutions to their problems.

I'd like to imply that the KB will have a lot of information in it, but don't want to suggest that it'll cover everything the user could ever need, as comprehensive does. Vast also feels like it's implying that the KB will be ... well, vast, which it won't necessarily.

Is there a more suitable word?

    How about significant? That's often used as a sort of soft antonym to trivial. – Dan Bron May 1 '15 at 9:56

    Possibly "detailed", although that implies more depth than breadth. – Matthew Read May 1 '15 at 17:40

    It's probably worth pointing out that comprehensive doesn't mean everything, it means everything, or much, or most, or a large proportion of. see thefreedictionary.com/comprehensive – Frank May 1 '15 at 18:24

Extensive may suggest a wide but not full coverage:

  • having wide or considerable extent, extensive reading. (M-W)
  • I think I'll go with this; as mentioned in comments on Sobrique's answer it may be redundant anyhow, but I'm OK with that in this situation – Joe May 1 '15 at 10:13
  • Similar but stronger: Exhaustive? – David Pugh May 1 '15 at 11:31

    @DavidPugh: I'm -1 on Exhausive. It implies you've totally exhausted the problem space, that you cover everything under the sun. – Kevin May 1 '15 at 15:09
  • @Kevin: Fair cop, guv. I'd forgotten or filtered out the negative in Joe's question. I shall give to charity. – David Pugh May 1 '15 at 15:16

There are two aspects or dimensions when describing how much knowledge or information is present somewhere: breadth and depth. Breadth refers to the extent of the topics covered; depth refers to the thoroughness with which each topic is treated.

"Vast", to me, primarily implies breadth, while "comprehensive" implies both.

So I would recommend first determining whether you want to emphasize the breadth, depth, or both of the KB, and then just...use one or both of those words. My instinct is that "broad" is probably the word you should pick--it is simple and clear.



dealing with or knowing a subject thoroughly or completely

    That also feels a bit too much like it's promising a fully definitive KB - I'm more angling for a sort of "most of your problems will be solved here" kind of word – Joe May 1 '15 at 9:50
  • Surely that's already implicit in 'knowedgebase'? – Sobrique May 1 '15 at 9:52
  • This is a fair point. It's certainly possible that I just don't need a qualifying word; marketing-speak sometimes makes you forget that you already have a word saying that thing :P – Joe May 1 '15 at 9:57

"While not definitive, the knowledge base provides a valuable resource for users."

definitive as in:

most reliable or complete, as of a text, author, criticism, study, or the like

  • Extensive was already suggested. – curiousdannii May 1 '15 at 15:41

    The key words are "not definitive". I can remove the use of the word extensive though. – Rich C May 1 '15 at 16:56
  • Oh, I see now. Definitiveness carries the idea of officialness and finality I think - but there are lots of official and final documents which are not fully comprehensive. – curiousdannii May 1 '15 at 17:37
  • @curiousdannii Good point. – Rich C May 1 '15 at 17:51
