just in case you are unaware of it, are you using the Nastran Documentation search functionality?
When you open the Nastran documentation package in adobe reader it has a "magnifying glass" search icon to the right of the title, using this enables a search across ALL the pdf documents in the Nastran library set. If you were unaware of it then do give it a go, it will probably return far more links than you want but I find it a help. This search will also search the release guides of every MSCNastran version and not just the latest; this is vey useful as new functionality is often described in detail in the release guide of the version it was introduced.
