Advanced review version search options

Not all roles grant access to review version search. If you need access, please contact support@cochrane.org.

Review version search is an Advanced Search for specific published review versions. It allows specification of detailed search criteria relating to the content of the searched document versions. The results can be exported as specific data from the hits, such as the number of included studies or the Authors' conclusions section.

For example, you can

search only in reviews where the Declaration of interest section contains the word 'none'.
search only in the reviews published in Issue 4, 2008,
search in all issues of 2007 for reviews from the Stroke group.

The main differences between Review Version Search and Document search are listed in the following table:

	Document search for reviews	Review version search
Type of result	Review documents	Individual published versions
Possible results per review	One	More than one

Search in contents	General, free text only	Section specific, can also be on number of elements
Export options	Attributes only	Attributes and content - see Export options for review versions

Warning: You cannot use a single string containing information from several different review elements. For instance, since references are stored in a highly structured format, the search string 'New England Journal of Medicine 1977;297:686-91' contains information from several different elements and the punctuation is added when displaying the review.

Warning: Numbers in the Data and Analysis section cannot be used as search terms as all the numbers are stored in a way that prevents this.
