Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

RFC # 628 SRI-ARC
NIC # 22361 March 27, 1974
Status of RFC Numbers and a
Note on Pre-assigned Journal Numbers
This is to announce that RFC numbers can now be obtained on-line through
NLS at OFFICE-1; they can no longer be obtained on-line at SRI-ARC.
You may still call the NIC to get an RFC number, if you do not wish to
use the on-line facilities.
Also, please note that pre-assigned journal numbers (excepting RFC
numbers) can be used through NLS only on the system (OFFICE-1 or SRI-
ARC) from which they were taken.
