We have a site with a document library that has a number of files in
that library. Many MS Word files in this library start with a file
names like such:
CSD-OP-ST...
CSD-OP-GU... (there are 6 files out there with this prefix)

if I do a search for "csd" (without the quotes) only 4 of the six show
up in the search results... yet if I put the full filename in the
search box it comes up fine... any ideas what I can do to resolve this?
