I. Match all words searching is equivalent to searching using these default search boxes on ODS Basic Search:
Use Match all words
when the search terms do not appear as a phrase in the UN documents. For instance, you want to find documents about the protection and conservation of environment. Hence,
Match all words: environment protection conservation
Omit common words (stop words) such as: and, the, of, a, an, on, in, etc in Match all words searching.
II. Exact Phrase searching as its name suggests, involves searching for UN documents that contain a given phrase e.g., green economy, peacekeeping operations, University for Peace, assistance in mine action, effects of atomic radiation. The phrases have to be entered as they are in the search query even when they contain common words such as in, of. For example,
Exact Phrase: university for peace
You can also perform exact phrase searching using the default search boxes on ODS Basic Search by inserting quotes (") before and after the phrase, or inserting a period (.) between the words of the phrase. For example,
"assistance in mine action"
III. Any Word searching may be used when a search term has synonyms or variant spellings, or when you are looking for UN documents that contain at least one of the search terms. For example:
Any Word: Bombay Mumbai
Any Word: Macau Macao
Any Word: Tiger Lion Elephant
Avoid using phrases in Any Word searching.
You can also perform Any Word searching using the default search boxes on ODS Basic Search by inserting OR between the search words, i.e.,
Bombay OR Mumbai
Macau OR Macao
Tiger OR Lion OR Elephant
IV. Exclude searching has to be used in conjunction with other search field(s). For example, my search is retrieving documents about Democratic People's Republic of Korea when I want documents about Republic of Korea. So I exclude the phrase "Democratic People's" in my search:
Match all words: Korea
Exclude: "Democratic People's"
V. Words in the title searching will give more precise results than Match all words searching since only documents containing the search terms in their title will be retrieved. Examples:
Words in the title: security council resolution
Words in the title: resolution adopted general assembly
Omit quotation marks or other punctuation for Words in the title searching.
