SEARCH HELP

WHAT HAPPENS WHEN YOU ENTER TERMS INTO THE SEARCH BOX?

By default, when you enter one or more terms in the search box, the following happens:

  1. Term(s) will be searched in all fields of the articles and across all journals
    • Use the pull down menu to limit your search to content from within a specific journal
  1. Search is case insensitive. Searching ASIA, Asia or asia will all give the same results.
  1. Terms are automatically stemmed eliminating the need to manually type common variations for your search term. Variants that are found include:
    • Linguistic variants: Searching CLEAR will find its grammatical variants including clear, clears, cleared, clearing, clearer, and clearest
      • Searching any variants (e.g., CLEARED) will also find all term variants.
    • Common British vs. American spelling variants: Searching CENTER finds center, centers, centre, and centres
    • Non-standard plural variants: Searching MOUSE finds mouse and mice
    • Common irregular verbs: Searching RUN finds run, ran, runs and running
      • Searching any variants (e.g. RUNNING) will also find all term variants.

NOTE: Users can also search with wildcard characters to find all variants for a root term. See “Search Conventions” chart below for more information on using wildcards.

  1. If you enter two or more search terms, such as AIR POLLUTION, the search will AND the terms finding any articles where both terms, air AND pollution, appear anywhere in the article.
    • Phrase Searching: To find an exact phrase, place the terms in quotation marks (“ “). The search, “AIR POLUTION” finds articles where the exact phrase, air pollution, appears anywhere in the article

SEARCH CONVENTIONS

The following list summarizes information on how terms are processed by the search and conventions that can be used in your searches

How to search for

Example

Use

Single term

mining

Searches for specific term in article or selected fields.

NOTE: Variants based on automatic stemming rules (see above) will also be found. MINING finds mining, mine, mines and mined

Multiple words

air pollution

If no quotes are used, search will “AND” terms and find articles or selected fields where both terms appear. NOTE: Variants based on automatic stemming (see above) will also be found.

Phrase Searching

“air pollution”

Use quotes to find exact phrases. This search finds the exact phrase air pollution in the article or selected fields.

“aerosol emission”

Automatic stemming is also applied for phrase searching so both singular and plural forms of the word will be found. In this case, aerosol emission or aerosol emissions will be found

Wildcard (or truncation)

measure*

Use an asterisk (*) to match all terms beginning with a word root. MEASURE* finds terms beginning with the word measure including measure, measures, and measurement. The word root must contain at least three characters.

*spheric

Use an asterisk (*) at the beginning of a word to match terms with the same suffix. *spheric will match ionospheric or thermospheric. The word root must have at least three characters.

tum*r

Use an asterisk to match multiple characters within a word. tum*r will match both tumor and tumour

wom?n

Use a question mark (?) to match a single character within a word. wom?n will match women or woman

Hyphenated phrases

“ground water”

DO NOT USE ground-water

For terms that generally are hyphenated in the text, e.g. ground-water, do not include the hyphen when searching. Hyphen should be retained when searching for an ISSN or DOI

Logical operators in phrases

“Food and Drug Administration”

To find phrases which contain a logical operator (and,or not), search using quotes.


SUPPORT FOR LOGICAL (BOOLEAN) OPERATORS:

The following operators can be used to broaden or narrow your search results by entering them directly in the search box.

Operator

Example

Use

AND

moon AND craters

Both terms MUST appear in the article or selected field(s).

OR

earthquake OR landslide

At least one of the terms must appear in the article or selected field(s)

NOT

mercury NOT planet

The first word must appear but the second word cannot appear in the article or selected field(s)

ORDER OF PRECEDENCE

NOT

AND

OR

If your search contains more than one of these logical operators, the system will execute the search in the following order:

  1. All NOT operations first,

  2. All AND operations second

  3. All OR operations last

This order can be changed by using nesting (see below).

Grouping (or nesting)

(moon OR lunar) AND craters

Default precedence order can be changed by using parentheses () to explicitly group searches using logical operators.

Proximity Operators

NEAR

NEXT

NEAR

earth NEAR surface

By default, NEAR finds terms within 6 words of each other in either order. Earth NEAR surface finds “earth surfaces” and “surfaces of the earth”.

NEAR/x

remote near/5 sensing

Finds terms within x words of each other in either order. User can decide the number of words between terms using the /x where x = the maximum number of words between search terms

NEXT

earth NEXT surface

Terms must appear in the order keyed and assumes terms are next to each other. Earth NEXT surface finds earth surface but not “surface of the earth”

In addition to the above functionality, you can also limit your search terms to specific fields. The chart below lists the available field labels, information on each searchable field and sample searches.
