The following information is provided so you can see what's new on the Quertle site. Much of what will be new in the coming versions will be based on your input. Please give us your feedback so that Quertle meets your needs.

v3.3

• What You Won't See - There is a lot new with this release, but it is almost entirely "under the covers". Changes were made to improve performance, accuracy, and document retrieval.
• What You Will See
  
  • Update to the Home page design
  • Ontology changes that result in even more relevant results

v3.2

• Alerts - Quertle now supports automated Alerts. For each saved search in your MyQuertle profile, you can choose whether or not to receive a weekly email Alert showing new documents that meet your saved search criteria. And, with a simple one-click link, you can view dynamically explore those new documents on the Quertle web site.
• New Power Terms - Several new Power Terms have been added including automatic Power Terms for "polymer", "biopolymer", and "synthetic polymer". The full list of Power Terms is here.

v3.1

• Search Suggestions - As you enter your search, Quertle now offers suggestions for completing the query. Unlike other sites where the suggestions are based on what other users have searched for, Quertle provides semantic suggestions based on facts stated in the documents, helping you find what matters.
• Support for Linking to Library Subscriptions Expanded to >1000 Organizations - Thanks to requests from users and librarians around the world, Quertle results can now be connected to library subscriptions for many more organizations. Simply create a MyQuertle account, choose your organization from the drop-down list, and the My Library link next to the retrieved documents will take you through your library to the article. Need your organization added to the list? Click here to submit a request. It's free.

v3.0

• MyQuertle - Allows users to save searches (including any applied filters) and easily re-execute them. By indicating an organizational affiliation, users will also be able to access documents through their institutional library subscriptions (previously done using a drop-down list on the Results page). MyQuertle also allows users to indicate their preference for the number of results to show on each page. This version lays the foundation for future MyQuertle functions, including automatic alerts and more user preferences - both coming soon.
• New Power Terms - Many new Power Terms have been added at the request of users. Additions include $Hormones, $IonChannels, $NuclearHomoneReceptors, $Enzymes, and $AlternativeModels (lower organisms and in vitro systems). The full list of Power Terms is here. Still missing what you want? Let us know.
• Improved Journal Searching - Quertle now supports searching for journals using non-official, but popular abbreviations (such as PNAS). If we didn't catch an abbreviation you want, please let us know.
• Publication Types - Quertle has added Video Audio Media as a publication type to assist in finding videos and other multimedia documents.
• Connection to Institutional Subscriptions (Link Resolving) - As requested by many libraries, Quertle has added the ISSN and PMID to all OpenURL requests.
• Additional Improvements - Many changes "under the covers" have been made to improve performance, precision, and recall.

v2.6.1

• User-selection of Institutional Subscriptions - Users can now select their organization (on the Results page) to activate the "My Library" links. This enables users off-campus to easily connect to subscriptions. This is also for institutions that have not yet signed up for automatic recognition. To request adding your institution to the drop-down list or to request automatic recognition, contact us.
• Easy Access to Resources - By request, Quertle has added a new Resources link at the bottom of each page giving quick access to the Quertle movie, training materials, browser tools, and resources for adding Quertle to your own web page.

v2.6

• More Content - The NIH RePORTER database of grant applications and the National Library of Medicine TOXLINE database of biochemical, pharmacological, physiological, and toxicological effects of drugs and other chemicals have been added to Quertle's relationship-based searching.
• More Access to Articles - If your organization has registered with Quertle, your institutional subscriptions will be accessible through the "My Library" link. Registration is simple and completely free. Contact us for more information on link resolving.
• Additional Document Highlighting - In general, Quertle displays sentences that contain one or more relationships (subject-verb-object triplets) that match your query (or in the case of Keyword searching, the best matching sentence). In each case, the search terms are highlighted in that text, as well as in the document title. When you limit the results using, for example, the Also Containing filter, the matching term may be found elsewhere within the meaningful document content (e.g., elsewhere in the body of the document, in the MeSH terms, etc.). In such cases, Quertle now shows the matching text with the matching term(s) highlighted.

v2.5

• Export - You can now select and export references. RIS and MODS format are both supported. Quertle is also now Zotero compatible for direct export of references from any Results page.
• More Full-text - Quertle now indexes all the Open Access content from PubMed Central.
• More Links - Quertle continues its ongoing efforts to expand the links available for one-click access to documents, including PDFs.

v2.3

• Searching by Chemical ID - You can now search for literature on specific chemicals using a variety of IDs. For example, use EINECS 216-353-0, BRN 1428746, or 1563-66-2 to find carbofuran.
• Distinguish between CCL4 (the chemokine) and CCl4 (carbon tetrachloride) - Logic was added to enable these two entities to be distinguished. Use the proper capitalization and you will now get what you wanted.
• New Power Terms™ - The list of Power Terms™ continues to expand, thanks to suggestions from Quertle users. Keep the feedback coming in.
• New Resources - Links are provided on the Home Page to a one-sheet tri-fold guide for using Quertle and a user's guide with Quertle Tips.

v2.2

• Highlighting of Author Names - Now when you search for an author, that name will be highlighted in the results.
• New Power Terms™ - The list of Power Terms™ continues to expand, thanks to suggestions from Quertle users. Keep the feedback coming in.
• Updated Home Page - More information has been added to the Home Page.

v2.1

• More Content - Quertle's content has been expanded as part of its ongoing efforts to provide all the relevant information in a single search interface. Now you can search News Reports (as reported by FierceMarkets Life Sciences and Health Care), so that new discoveries and information can be found before it is published in the literature. Quertle also has added scientific whitepapers and research posters that otherwise do not appear in the literature.
• Searching for Multiple Authors - Based on user feedback, Quertle has changed the behavior of searching for multiple authors. When you enter more than one author, only documents that contain all of the names will be reported in the results.
• Google Translator - Google's Translator has been added to the bottom of each page to assist researchers whose primary language is not English.
• New Power Terms™ - The list of Power Terms™ continues to expand, thanks to suggestions from Quertle users. Keep the feedback coming in.

v2.0

• New Interface - Based on user feedback, the interface for the Quertle site has undergone a major revision. Keep the feedback coming in.
• Full-text Documents - Quertle introduces the first full-text documents, covering the entire collection of journals (more than 200) from BioMed Central. More full-text sources will be coming soon!
• Results are now Organized by Document - Previously, each relationship was presented separately. Now, based on user feedback, Quertle presents the relevant relationships from each document together.
• Sorting Results by Date - Users now have the option to sort results by date, in addition to the default ordering by relevance.
• New Power Terms™ - Many additional Power Terms, as requested by users, have been added.

v1.2

• Expanded Power Terms - By popular demand, the list of Power Terms (query terms that represent entire classes of objects) has again been significantly expanded. The new Power Terms include additional categories such as $FunctionalClass (representing protein functional classes like chemosensors or recombinases), $CellLines (representing any cell line), and others.
  
  Quertle also introduces "automatic" Power Terms. Unlike the regular Power Terms, which specifically exclude the query term itself (for example, $Proteins finds any protein but NOT the word "protein"), automatic power terms find the query term as well as members of its category. Examples include "blood cancer", "flavones", "glycoprotein hormones", and many more. The "automatic" Power Terms do not require a $.
  
  Check here for the full list of regular and automatic Power Terms. Continue to let us know what Power Terms would help your searching!
  
  
• "Behind the Scenes" Updates - Quertle has updated some of the searching mechanics, including searching MeSH terms for keywords, to ensure the most relevant results are found.
