Introduction

The new site currently searches two databases: Meeting Abstracts and Health Services Research Projects in Progress (HSRProj). The Meeting Abstracts database contains selected abstracts from meetings and conferences in the subject areas of AIDS, Health Services Research, and Space Life Sciences. HSRProj contains descriptions of research funded by federal and private grants and contracts for use by policy makers, managers, clinicians and other decision makers. It provides access to information about health services research in progress before results are available in a published form.

The Search Page

NLM Gateway search page

The Gateway search box is at the top of each page.
The Gateway Features bar includes Home, About, and Help.
The Gateway bottom bar contains Contact Us and administrative links.

Searching

Enter search terms in the query box.

Click on "Search" or hit "Enter".

The query box is on every page. You do not need to return to the home page to enter a new search.

The default is a subject search.
Enter one or more search terms in the query box and click on "Search" or hit "Enter".
The maximum length for user input is five hundred (500) characters.
Search terms are automatically combined (ANDed) together.
Gateway ignores stopwords in subject search queries that are not part of a phrase. There are six stopwords in the Gateway: a, an, and, not, or, the.

Boolean Operators

The Boolean operators AND, OR, and NOT are available.

Intersection (AND) - retrieves items that contain all the terms.

Union (OR) - retrieves items that contain one or more of the terms.

Difference (NOT) - excludes items that contain the term(s).

The default operator is AND.

Boolean operators AND, OR, NOT must be in upper case (e.g., vitamin C OR zinc).

The Gateway processes the AND and OR Boolean operators in a left-to-right sequence.

The NOT operator is processed first.

Nesting: You can change the order in which the Gateway processes the AND and OR operators in a search statement by enclosing the unit in parentheses. The terms inside the set of parentheses will be processed as a unit and then incorporated into the overall search strategy.

AND two or more search terms.
heart +lung
heart AND kidney

OR operator:
heart || lung
heart OR kidney

NOT operator:
heart -kidney
heart NOT kidney

Proximity (within 4 words):
"heart lung"~4

Wild card
heart*

Complex query:
(heart +lung) OR (liver NOT kidney)

Searching by Fields

Field names (case sensitive, first letter is capitalized and some internal letters are capitalized as in PerformingOrganization) followed by a colon should be entered before the search term or terms.
Unqualified terms should be entered after all qualified terms, or should be separated with a Boolean operator (AND, OR, NOT).

Examples:

Title: (heart + kidney)
Mesh: (lung AND cancer)
Author: Smith

Notes:

The Allowable Search Field Descriptions below list allowable field qualifiers.
A table of all collections and the allowable search fields is available.

Author Name Searching

Enter Author: followed by last name or the last name and initial(s) (no punctuation);

You may search for multiple authors too (see examples below).
Author: Kovacs
Author: "Smith R"
Author: "Freed GL"
Author: ("Freed G" OR "Freed GL")
or
Author: "Freed G" OR Author: "Freed GL"
Author: (Freed AND Smith)

You may search for multiple authors at one time.
You may enter only the last name, or the last name and the first initial if you do not know the middle initial.

Notes:

You can search for HSRProj investigators using the author field qualifier.
HSRProj investigator names are displayed as full names, but must be searched in the format last name plus initials (no punctuation).
If you search for only an author name, collections without authors will not be searched.

Title Searching

Enter Title: followed by one or more title words
Title: AIDS
Title: (sexually transmitted diseases)
Title: (lyme disease)

You may enter a complete title, or one or more words or phrases found in the title.

MeSH Searching

The Medical Subject Headings (MeSH) comprise NLM's controlled vocabulary used for indexing articles, for cataloging books and other holdings, and for searching MeSH-indexed databases. MeSH terminology provides a consistent way to retrieve information that may use different terminology for the same concepts.

Enter Mesh: followed by the MeSH term.
Mesh: (Lyme Disease)
Mesh: (Myocardial Infarction)

You may search for multiple MeSH terms at one time.

Searching on Year fields

For Meeting Abstracts:
PubDateYear: 2010
PubDateYear: [2006 TO 2010]

For Hsrproj:
InitialYear: 2009
FinalYear: 2011
FinalYear: [2010 TO 2011]

Allowable Search Field Descriptions

Author - Enter the field qualifier followed by the author name in the format last name plus initials (no punctuation). Additional information is in the Author Name Searching section.

MeSH - To search for a MeSH term, enter the field qualifier followed by the MeSH term. Additional information about MeSH searching may be found in the MeSH Searching section.

Title - Enter the field qualifier followed by one or more title words. Additional information about title searching may be found in the Title Searching section.

UI - A unique identifier for an item. PubMed IDs (PMIDs) may be searched using the Unique Identifier field qualifier(e.g., UI: 11054795).

Notes:

A table of all collections and the allowable search fields is available.

Searching for Conferences

For Meeting Abstracts collection, Enter CollectiveName: followed by Conference Name in search format.

CollectiveName: (International Conference on AIDS)
CollectiveName: AcademyHealth. Meeting AND Author: "Mehrotra A"
CollectiveName: International Conference on AIDS AND PubDateYear: 2010
