Below is the complete guide to searching DTIC's collections.


Navigation Tools

Using the Navigation Bar
The navigation bar at the top of each screen will help you easily go from one section of STINET's Web site to another. Each page in the Search Web site is represented by words on the navigation bar.

Using the Navigation Buttons
The navigation buttons on the left hand side of the search pages will also help you easily go from one section of STINET's Web site to another. Each link in the Search Web navigaional buttons are described below.

DTIC Collections
DTIC's collection includes areas normally associated with Defense research; however, since DoD's interests are widespread, the collection also contains information relating to: basic sciences such as Biological and Medical Sciences and Environmental Pollution and Control; Behavioral and Social Sciences; DoD Directives and Instructions; budget estimates and Research and Development Descriptive Summaries (RDDS); Conference and Symposia Proceedings; and patents and patent applications. DTIC also makes software, videos and journal articles available as well.

Special Collections
These collections are specific cuts of DTIC's Technical Reports Collection. Some collections may be sets of full text reports or citations relating to an underlying theme. Others may be searches designed by DTIC to allow users to easily find documents on a certain broad topic in the Technical Reports Collection. Others may even be a featured report which may be of extra importance or interest.

Multisearch
STINET MultiSearch has been implemented as another service to our DTIC customers. This web-based service is designed to be your portal to the Deep-Web for Scientific & Technical Information. The Deep-Web is content that resides in searchable databases and can only be accessed via a direct query to the database. Since this content is not published as static web pages, it is not available on the "surface" Web and cannot be accessed directly through commercial and government search engines


Journals
Air University Library's Index to Military Periodicals - This is DTIC's electronic version of the AULIMP (Air University Library's Index to Military Periodicals). Searching and browsing features will guide you through thousands of citations to articles, editorials and news items appearing in over 80 military and aeronautical periodicals indexed by Air University Library, Maxwell AFB. The site contains citations and some full-text articles from 1990 to the present and quarterly updates offer you current information in your subject of interest. Links to electronic journals are also provided when available.

Staff College Automated Military Periodicals Index - This is DTIC's electronic version SCAMPI, the Joint Forces Staff College's "Staff College Automated Military Periodical Index". The Joint Forces Staff College Library is a specialized military library, focusing on research in joint and multinational operations, military history and naval science, operational warfare, and operations other than war. Library staff members regularly scan the weekly news magazines, monthly and bimonthly journals such as Military Review, Armed Forces Journal, and quarterly publications, including NATO's Nations and Partners for Peace, RUSI Journal, and the Naval War College Review. Miscellaneous reports from RAND and the General Accounting Office are also indexed for SCAMPI. The resulting database serves as a current (1997 - present) guide to articles on military and naval art and science, operational warfare, joint planning, national and international politics, and other areas researched by JFSC faculty, staff, and students. The index is updated quarterly. Retrospective conversion for records from the past 40+ years is ongoing.

Other Resources
Resources are links to research, development, and acquisition resources produced by DTIC. Joint Resources are links to resources which DTIC has produced for, or in coordination with, other organizations. Related Web Links are links to resources which are not affiliated to DTIC but provide information valuable to the Defense community.

MCTL
The Militarily Critical Technologies List (MCTL) is a documented snapshot in time of the ongoing DoD MCTL Process. The technologies included in the DoD MCTL support the Joint Chiefs of Staff (JCS) objectives. The are two versions, the Public Distribution MCTL and a Limited Distribution MCTL which is restricted to the DoD and available on Private STINET


Search Tips

Case Sensitivity
Searches on DTIC's collections are not case sensitive. Use either upper-case or lower-case letters.

Boolean Operators
Boolean operators are used to increase, decrease, and refine search results. Boolean operators are AND, OR, NOT. Note: The default Boolean is OR.

Examples :

AND: To locate documents containing the words environmental and hazards enter: environmental and hazards.

OR: To locate documents containing the words nuclear or submarines enter: nuclear submarines. Remember, OR is the default operator. You do not need to key in the OR because it is automatically implied if no other Boolean is entered.

NOT: Not is used to negate words or phrases from your search query. To invoke the NOT operator you must immediately precede it with the word AND. To locate documents about all vehicles except armored vehicles, enter: vehicles and not armored.

It is important to note that unlike some search engines, boolean operators are not case-sensitive when searching DTIC's collections.

Strict vs. Fuzzy Logic
Strict Logic searching imposes precise control over your search results. This type of searching will often eliminate useful results because it conforms exactly to the words the user enters. Strict Logic searching is usually the preferred method of sea rchers seeking documentation on a specific discipline.

Fuzzy Logic searching allows a more relaxed search environment than Strict Logic. Unlike Strict Logic searches, Fuzzy searching will include the retrieval of documents that contain only some of the words the user enters. Note: Fuzzy Logic search ing requires that the Max Docs Returned be set to All.

Example: "armored vehicles" and combat, will retrieve 7840 citations. The same search using Strict Logic will retrieve 265 citations. Caution: Fuzzy Logic searches require more processing time. Be prepared to wait.

Phrase Searching (adjacency)
To locate documents containing a phrase, the words must be enclosed in quotation marks. This function ensures that one word is followed directly by another in the retrieved documents.

Example : "chemical compounds" retrieves documents containing the word chemical directly adjacent to compounds, (with no other words between). Note: Phrase searching is effective for complete text and most fielded searching. This function was formerly represented in STINET by the ADJ operator. This operator is no longer a part of searching DTIC's Collections.

Proximity Searching
Proximity searching provides a method of locating citations in which the words you enter appear within a defined distance of each other. This allows you to receive more accurate results.

Note : Proximity searching is bi-directional.

The syntax used for proximity searching is as follows : term1 within numberofwords term2. Note that the search engine represents one word as 20 individual characters.

Example : To locate documents with the word aeroelastic within 8 words of composite enter the following: aeroelastic within 8 composite

Truncation
Truncation is a method of reducing a word to its root in order to retrieve all of the word's variations. Truncation is represented by both the * and % characters. Truncation is bi-directional.

Example : "connect*" or "connect%", will retrieve documents on connect, connects, connector, and connectivity. "*polar" or "%polar" will retrieve bipolar and unipolar.

Report Date Searching
Report date searching may be accomplished in two ways, specific date and date range. All dates should be entered in the format YYYY-MM-DD. (Y - year, M - month, D - day)

Examples Specific Date Search : To search for documents with a report date of March 5, 1986 you MUST enter the date as 1986-03-05. NOTE : When searching for a specific date, you must enter the same date in the "From" box, and "To" box.

Date Range Search : To search for documents with report dates that span a number of years, enter the start date in the "From" box and the end date in the "To" box.

Searching on the Title Field
If it is known that a title contains punctuation, you MUST enter it with punctuation enclosed in quotation marks. Example: "quasi-three-level lasers". Phrase searching and Boolean operators can be helpful when searching for titles where a limited number of words are known. Example: "quasi three" will retrieve citations that contain those two words next to each other in the title field. The AND Boolean operator will retrieve citations where both words are present somewhere in the field. Example: "quasi and level"

Sorting Search Results
The search engine provides multiple sort options. The system automatically defaults to term frequency count. This means that the highest ranking document in your search results is based on the number of occurrences.

Search results can be sorted by various secondary fields such as date, personal author, corporate author, and accession number. REMEMBER: The primary sort of your search results is based on term frequency count, and thereafter on your ch oice of secondary sort options.

Note : The sort default is set to ascending order, i.e., A-Z for all fields except date fields. Date fields are set to descending order, i.e., latest to oldest.

Special Characters
Terms/phrases or numbers which contain special characters must be enclosed in quotation marks. Examples: "c4is&r;", or "f19628-84-c-0001"

Stop Words
There are no stop words. All words may be used in a search. Note: Stop words are words that are so common and used so often that they were not indexed for search and retrieval purposes. Many older databases and search engines do not allow the use of stop words in a search statement.
