ecoi.net allows you to search the full text of more than 300.000 documents. This page explains how to combine search terms and use filters.

How do I combine search terms?

AND

The AND operator (in all capital letters) is the connection used as default when no operator is given.

It finds documents containing all the search terms.

"Tamil Tigers" AND government AND talks
"Tamil Tigers" government talks

both lead to the same results: finding documents containing the phrase Tamil Tigers, and the term government, and the term talks

OR

The OR operator (in all capital letters) finds documents containing one of the search terms

conscription OR desertion

finds documents containing either conscription, or desertion, or both

NOT

The NOT operator (in all capital letters) excludes search terms:

genocide NOT Darfur

finds documents containing the term genocide, but not the term Darfur

How do I group search terms?

"..."

Quotation marks define a group of words as phrase and search for the whole phrase.

"organised crime"

finds documents containing the whole phrase organised crime

(...)

Search operators can be grouped logically using parentheses.

(homosexual OR lesbian) AND discrimination

finds documents containing the term discrimination, and either homosexual or lesbian

"... ..."~n

Proximity Search is represented by quotation marks, followed by a tilde ~ and a number.
It finds terms that are within a distance of n words from each other

"amnesty rebels"~5

finds documents containing the terms amnesty and rebels within a distance of 5 words from each other

How do I search for spelling variations?

ecoi.net's full-text search is supported by a bilingual thesaurus developed specifically for the context of COI: terms which are included in the COI Thesaurus are automatically searched in both English and German. Spelling variations and synonyms are also automatically included in your search for these terms. If necessary, you may switch off this feature by de-selecting the checkbox next to the search term field ("Use synonyms"). To find out more, please read our blog post on the COI Thesaurus.

Furthermore, the following functions help you finding spelling variations:

*

Wildcard search: an asterisk * serves as placeholder for any number of characters (from zero to many, within one word)

homosex*

finds documents containing words beginning with homosex, for instance: homosexual, homosexuals, homosexuality, as well as the German words homosexuell, Homosexualit├Ąt, etc.

~

Fuzzy Search, represented by a tilde ~ at the end of a word, finds words that are spelled in a similar way as your search term

Qanuni~

finds documents that contain, for instance, Qanuni as well documents containing Qanooni

How do I use filters?

You can refine your search using filters on:

- Country
- Source
- Document type
- Document language
- Publication date

You can select more than one filter, and you can choose how to apply the filters. For instance, you can either limit your search to maps, or exclude maps from your search, by selecting Maps as filter for "document type" and then choosing the appropriate operator in the drop-down.

As another example, you can select multiple sources and choose the "OR" operator (which is enabled by default) to receive documents from any of the selected sources. To exclude specific sources from your results, change the operator to "NOT".

Searching for a document for which you know the ecoi.net ID

If you know the ecoi.net ID number of a document, you can access the document by searching for # followed by the number. For instance: To perform an ID-search for a report of the UN Security Council with the ecoi.net ID number 238354, you enter #238354 into the search field and start the search. This will lead you to the report: http://www.ecoi.net/doc/238354
