Cochrane Search Indexing Issue
The Cochrane Database Systematic Reviews (CDSR) is currently experiencing some search indexing problem, affecting a small number of Reviews & Protocols published since 30 May, 2017. Some of the newly published content is are not being returned in search results, or users are experiencing the returned links are going to older versions of the review. We are advising that if directed to an older version from the search, users should use the “View current version” to get to the latest version.
Author teams are advised to review the 'missing' search content, and check that all the dates are accurate in the references, (with no text included) as this is a known issue fix for some indexing issues.
CENTRAL records are not affected. We are continuing to work on resolving this complex indexing issue.
CENTRAL Publication Date - An update
We are pleased to advise you that the problem with the publication dates in the first four issues of the Cochrane Central Register of Controlled Trials (CENTRAL) for 2017 (Jan-Apr) has been resolved. This problem affected the dates displayed in search results display, date limits, and exported dates for approximately 10% of CENTRAL records.
With the implementation of the solution, CENTRAL is now back to normal.
The final task is to remove those CENTRAL records that have been deemed redundant, and delete them from the database. This process will be completed shortly. Until completion of this task, users may experience <1% of links that fail to return a valid CENTRAL record.
If you have any queries, regarding this activity, please contact David Hives firstname.lastname@example.org
Performance in rendering content from the Cochrane Library is resolved. If you experience a questionable delay while downloading your Review, or you receive a 'failed' message, we ask you to report your experience.
We ask for:
- Full name:
- Institution contact address (as applicable)
- Email address contact point
- Browser include version
- System platform (e.g. PC, Mac, smart phone)
- A full description of the incident, including what page you were on (include URL)
- What time this event occurred
- How long it took to render the page desired
- Ideally we would appreciate screen shots, too, so that we can visually clarify your description
If you can include this in an email to the customer support team with the title 'Cochrane', this will help the support team prioritise your case.
For institutional users and Cochrane complimentary access, please contact email@example.com
All other users should report performance issues, including images, to firstname.lastname@example.org.
Next scheduled maintenance
Saturday 26th August 2017
Cochrane Library, and the Wiley Online Library, undergoes scheduled maintenance for releases and upgrades.
During such periods ,no updates to the content of the Cochrane Library website are made. Cochrane Reviews and Protocols continue to be published and are searchable as the site is released with additional functionality, including changes to the homepage for improved user engagement and user experience.
Why is there downtime for maintenance?
Due to the nature of technology and its development, it has become standard practice throughout many organisations to have regular, scheduled, updates to systems. By taking this approach, there is a reduced risk to functionality and other systems. Users can also plan to avoid usage during these maintenance periods. The date above indicates an expectation of scheduled maintenance that may disrupt access and functionality of the Cochrane Library. The standard schedule for developer activities commences at 10am (UK Time), and will continue for 2 hours, although this is subject to change. Notifications of the expected downtime will be sent out in the week prior to the expected downtime to users on the Cochrane 'lists' (TSCs, MEs and Cochrane Library User Group).
