Well, you did not give detail on that, but I was surprised about the "topic" field for vignettes. Here (on a Debian/Linux system), for some vignettes, "topic" contains a file path, which - I guess - may have been used during installation of the package, but is no longer present on my system. E.g:

  topic
  "/tmp/RtmpMQhWJi/R.INSTALL494a2adb/AnnotationDbi/inst/doc/AnnotationDbi"   title
  "AnnotationDbi: How to use the \".db\" annotation packages"   Package
  "AnnotationDbi"

I would expect the "topic" field to always contain a string suitable for use as the "topic" parameter in vignette(). For some other vignettes() found by help.search() this is is working. I did not figure out a pattern, so far.

Besides that, while testing, I found that the dynamic help fails to display the result of
  help.search ("grid")
with this message:
  Error in .HTMLsearch(query) :
  number of items to replace is not a multiple of replacement length I note that in the matches of that query, several vignettes are listed twice. This probably indicates a problem in my installation, but may still be worth fixing.
