How To Use DISCO's Search Options To Yield More Accurate Results
DISCO’s intelligent indexing and tagging system enables the filtering of content by format, language, date ranges, locations, topics, industries etc., ensuring you get relevant content, quickly. And with DISCO’s advanced free text search, we support ‘Boolean Operators’ to enhance the relevance of the content you wish to find, yielding more precise searches.
Below is a guide to using DISCO’s search filters and Boolean Operators (e.g. simple words such as ‘AND’, ‘OR’, ‘NOT’ or ‘AND NOT’) as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results. This will save you time and effort by eliminating inappropriate results that would otherwise need to be reviewed before discarding.
To search for an exact phrase, write the exact phrase as is, without adding any operators or quotation marks.
Information Technology would retrieve articles containing this exact phrase within the title or body of the article.
You can use boolean operators (and, or, not) to connect and define the relationship between your search terms.
The AND operator
The AND operator matches articles where both terms exist anywhere in the text of a single article.
Obama and Trump
Articles retrieved contain both words; “Obama” and “Trump”.
Browser and Information Technology
Articles retrieved contain both the word “browser” and the exact phrase “information technology”.
The OR operator
When used, the OR operator will return results which include either, or both, of the terms.
Obama or Trump
Articles retrieved contain the word “Obama”, the word “Trump”, or both words.
Browser or Information Technology
Articles retrieved contain the word “Obama”, the exact phrase “Information Technology”, or both.
The NOT operator
The NOT operator excludes articles that contain the term(s) after NOT.
Obama not Trump
Articles retrieved contain the word “Obama”, but not the word “Trump”.
Browser not Information Technology
Articles retrieved contain the word “browser”, but not the exact phrase “information technology”.
The NOT operator cannot be used with just one term. For example, the following search will retrieve incorrect results:
A not statement helps you eliminate articles that matches the query after Not.
(Obama or Trump) not (Bush or Clinton)
The above search will retrieve articles with “Obama” or “Trump” in the title or body, but will exclude articles which include “Bush” or “Clinton”.
If you have included a NOT statement in your search, ensure you have parenthesis around the terms you wish to exclude. This will separate the search into terms you want, and terms you do not want.
Parenthesis with operators
You can use parentheses to group clauses to form sub-queries within your search.
(Obama or Trump) and United States
The above query searches for either “Obama” or “Trump”, and “United States”. Results will only show articles which include the term “United States”, and “Trump”, “Obama”, or both.
If you wish to treat a search operator (and, or, not) as a search term, you must enclose the entire phrase in quotation marks.
“Obama and Trump”
The above search will retrieve articles containing the phrase “Obama and Trump” exactly as it is written, rather than results containing the term “Obama”, as well as the term “Trump”, anywhere in the article, as it would using the AND operator.
A proximity search looks for terms that are within a specific distance from one another.
To perform a proximity search, add the tilde character ~ and a numeric value to the end of a search phrase.
The above search will return results which include the terms “Obama” and “Trump” within 10 words of each other.
The distance referred to here is the number of term movements needed to match the specified phrase. In the example above, if “Trump” and “Obama” were 10 spaces apart in a field, but “Trump” appeared before “Obama”, more than 10 term movements would be required to move the terms together and position “Trump” to the right of “Obama” with a space in between.
General tips for performing searches
Avoid placing two connectors next to each other, this will always retrieve incorrect results.
Obama and not Trump
Obama not Trump
Non-searchable characters are treated as whitespace in a search statement. The following punctuation marks are, therefore, optional in a search statement:
Hyphen or dash (-)
Exclamation point (!)
The apostrophe is searchable only if enclosed within 2 letters. For example, entering the search Coca Cola will retrieve the same results as the search Coca-Cola.
Pasting quotation marks from Microsoft Word
If you copy and paste a search statement containing quotation marks from a Microsoft Word document into the DISCO free text search box, you may still receive incorrect results. To correct this issue, remove the old quotes that were copied from Microsoft Word and insert new ones using your keyboard.
