A search operator is an instruction that joins keywords to form a new, more complex query. It enables you to look for several words at once by telling Copernic Desktop Search how to link keywords. The most common search operators are the three Boolean operators (AND/+, OR and NOT/-), which allow the inclusion or exclusion of documents from the search results.
Please note that you can also use quotes (exact phrase or whole word) and parentheses to create your
queries. You can customize Copernic Desktop
Search to always search for whole words. To
do so, check the Find whole words only checkbox
in the Advanced tab of the Options window.
| Description |
Example |
AND
(+)
Finds
documents that contain all of the
specified words.
Use
the AND operator to search for documents in which
all the terms joined with the AND operator are
present.
Therefore, if 4 keywords are joined
with AND in a search, only documents
containing all 4 keywords will be returned.
On the other hand, a document that
contains 3 of the 4 keywords will not
be returned. The AND operator
helps you narrow your search. By default,
Copernic Desktop Search uses the AND operator.
Be careful not to overuse the AND operator in a query; a search that is too specific could overlook relevant results. |
business AND meeting
Copernic
Desktop Search will find documents
that contain both "business" and "meeting".
Because AND is the default operator,
the following query would produce the
same results:
business
meeting |
OR
Finds
documents that contain at least one
of the specified words.
Use the OR operator to search for documents in which at least one of the search terms joined with the OR operator is present. The OR operator helps you broaden your search by including synonyms or related terms. |
meeting OR appointment
Copernic
Desktop Search will find documents
that include either one of the two
terms or both. |
NOT
(-)
Excludes
the documents that contain the specified
word.
Use
the NOT operator to ignore documents
that contain the specified words. The NOT operator
helps you narrow your search.
Be
careful with the use of NOT as the
attempt to narrow the search may
be too exclusive and eliminate relevant
documents.> |
meeting NOT appointment
Copernic
Desktop Search will find the documents
that contain the word "meeting" if
they do not contain the word "appointment".
Also,
if you search for references about "international
news", excluding the word "national" might
result in missing relevant results
whatever the context related to the
use of this word in documents. Therefore,
the NOT operator must be used
carefully. |
Quotation
marks
Finds
documents that contain the whole
word or the exact phrase.
Use quotation marks to avoid finding
similar terms or derived words. If
the word you are searching for needs
to be considered as a whole word, enclose
it in quotation marks.
The
documents must include the specified
whole word.
Quotation marks can also be used to search for an exact
phrase. |
"challenge"
Copernic
Desktop Search will find documents
that contain the exact word "challenge".
Had the word not been enclosed in quotation
marks, Copernic Desktop Search would
also have found documents containing
similar terms, such as "challenges" or "challenger".
"Lord of the Rings"
opernic
Desktop Search will find documents
that contain the exact phrase "Lord of the Rings". |
Parentheses
Processes the enclosed sub-query first.
Use parentheses to isolate parts of a query. Sub-queries included in parentheses are processed before all other parts of the query. |
(America OR Europe) AND maps
Copernic Desktop Search will first process the "America or Europe" sub-query to find all documents that include either one of the two terms or both. It will then filter all found documents to keep only the ones that also include the word "maps". Hence, it will find documents that contain the words "America and maps", "Europe and maps" or all three words.
|
@filename=
Finds documents that contain the specified word in the file name field.
Use the @filename= operator to search for documents by file name only. |
@filename=resume
Copernic Desktop Search will find documents that contain the word "resume" in their file name.
|
@all
Finds all documents.
Use the @all operator to display all documents of a given search category. |
|
Folder search
You can easily find a specific folder by grouping your results by folder. To do so, click the Arrange by: button and select Folder and Group Results. |

Remember: You can combine operators to create more refined queries.
