3. Search Hints
Term Search - input search strategy and specify fields to search such as author and title
- Punctuation
- Use quotes "" for exact phrases, i.e., "space shuttle"
- Use asterisk * for wild card to expand term searching, i.e., comput* searches for computation, computational, computer, computers, computerization, etc.
- Do not use hyphens in report and patent number searching, i.e., AIAA Paper 87 1746 (no punctuation)
- Do use hyphens for abstract, keyword, and title searches, i.e., x-ray
- Do not use slashes in any search, i.e., NASA NAVY
- Author
- Try searching for author in several ways
first initial last name, i.e., m nelson
first name last name, i.e., michael nelson
- Multiple Authors
Use last names only, i.e., yang hill
- Report and Patent Number Searches
- Leave all hyphens and slashes when entering report and patent numbers
- NASA-EP-251 report searched as "NASA-EP-251"
- AIAA Paper 2006-0069 report searched as "AIAA Paper 2006-0069"
- NASA-Case-KSC-12246-2 patent searched as "NASA-Case-KSC-12246-2"
Navigation Search - search by categories
- Initial search displays all available Navigation Search options: Collection, NASA Center, Publication Year, Subject, Availability Options, and Item/Media Type. As search progresses, Navigation Search options disappear when option is no longer applicable to a search set. Example, once + NACA is selected, the Collection option will not display
- Category options and number of corresponding citations displays, i.e., + NIX (111803) means that there are 111,803 citations in the NIX collection
- Use Item/Media Type to find NACA and NASA series reports
- Select + NACA to find reports (1915-1958)
- NACA report series: aircraft circulars, annual reports, technical memorandums, technical notes, reports, research memorandums, and wartime reports
- Select + NASA to find reports (1958-present)
- NASA Report series: conference paper, contractor report, educational publication, reference publication, special publication, technical notes, and technical translation
- Use Availability Options to find online documents
- Select + Online
- Select + PDF
