What is a similar word to "comprehensive" that doesn't suggest absolutely everything will be covered?

Solution 1:

Extensive may suggest a wide but not full coverage:

• having wide or considerable extent, extensive reading. (M-W)

Solution 2:

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.

Solution 3:
