Fixed a bug which truncated Article Title on Some Results
Fixed a bug where endnote Imports Only First Article
MeSH Terms: Articles from MEDLINE now include their Medical Subject Headings (MeSH) as keywords, to improve their discovery.
Search by Keywords: It is now possible to search by the keywords associated to an article, directly in the search box.
Advanced Search by Title, Abstract and Keywords: A new option has been added to the query builder in the Advanced Search, allowing you to search through a combination of an article’s title, abstract and keywords. This combination of fields provides optimal results for a query.
DOI Search: A bug which our search backend stopped recognizing Digital Object Identifiers in a query has been fixed.
Filter by Journal Name with Syntax Characters: We discovered that some journal names contain characters, such as slashes and ampersands, that our search backend would interpret as syntax characters for a complex search. Filtering your search results by such a journal name would result in an error message. This h
Filter by Open Access Type: 80% of the articles are now classified in our index based on the type of Open Access under which they are offered: Gold or Green. Results can be filtered by either or both types as well as include it as a search criteria in the Advanced Search. A helpful icon next to each result’s title will also indicate which type of Open Access that article is available under.
Better Handling of Undetermined Languages: We’ve improved how we classify article languages, which means a more accurate count for those articles where we can’t yet identify the language and better filtering in our aggregation panel.
More Browsers: We always try to provide the best user experience in oaFindr and that has required a modern web browser. However, we were rather conservative in which browsers had access to the application. We’ve now broadened our support and welcome users of Opera, Vivaldi and other modern browsers to oaFindr.
Copy Link Without Flash: The action button associated with each search result always offered a way to copy the article’s link to your clipboard, but it would use Flash in an attempt to do so. Our new solution does not need it anymore, which makes oaFindr Flash-free!
Tooltips: Some helpful tooltips on some elements of the search result page were missing. We’ve added them and hope they help.
Number of Search Results per Page: It was possible to alter the number of search results per page directly in the URL, but setting too high would cause the application to freeze, and that’s bad. We’ll now prevent a number of results that would degrade performance too much.
Exact Search: We always try to give you the best results for your query, but sometimes you know exactly what you want. Surrounding one or more search terms with double quotes (“”) will now return exact matches for those terms.
Faster Search: We’ve revamped our search system in a big way, which means both faster search and more accurate results.
Improved Articles Deduplication: Finding duplicate articles is a waste of your time, so we’ve improved our deduplication process to filter more of them out. We now have over 18 millions articles in our index, with fewer duplicates than ever.
Abstract Preview: Abstracts are a great way to find out whether an article is pertinent to your needs. We now show you the first three lines of an article’s abstract right in the search results, to make it easier or you to weed them out.
New Languages Filter: Our Language Filter is out of beta! It will show you the top five languages for the results of your query, with an option to expand the list and see all the languages represented in your result set.
New Years Filter: We’ve also improved the way the Years Filter works. We now show you the five latest years that have results in your search, with an option to expand the list and see all the years with articles in your result set.
New Message When Search Has No Result: When a search returned no results, we used to display a full page informing you of the fact. We’ll now just display a message, rather than send you away, letting you tweak your query to get better results.
Easier Date Selection in Advanced Search: Selecting a date range in our Advanced Search page was cumbersome, so we’ve made it easier to pick a range, or to choose from some common, useful ranges: Current and Past Year, Last 5 Years and Last 10 years.
Selecting All Subjects: When you selected all the subjects one by one, an empty subject criteria would be added to your query, and an error message would appear. We’ve taken care of that. Back Button Issues: We discovered one case where using the back button would not return you to your previous search, but reissue your current one. That’s now fixed.
Third Level of Subject Filters
With the objective of providing our users more precise results to their queries, we have implemented a 3rd level of subject headings. Due to the new level of article classification, we had to completely overhaul the way users select subjects to fit within the design of the site.
Filtering by article subject is now a process of selecting headings within a classification tree. Clicking on a check box next to a subject heading selects all articles under that heading. If the user wants to be more precise, they can click on the arrow next to the number of results to reach the next level of classification where they can choose the fields they want to search.
Once an arrow is clicked, a layer of related headings is shown, allowing the user to further narrow down their selection.
These updates on the search page also carry over onto the Advanced Search page where the user can navigate the full tree to select their fields in a more visible manner.
As this feature is rather dynamic we strongly encourage that you check out the new filtering systems on the site to get a better idea of how to filter by subject headings.
Index increased to over 12.5 Million articles
With a few adjustments made to our pipeline we were able to acquire over 2 million new articles which will soon be incorporated into our live index.
OaFindr is now available in Spanish
All feature from the search, the Help Center, and the attached chat have been translated to Spanish, making it the 3rd language available to our users.
Switching languages is easily done on any page of the product by clicking on the language the page is currently being displayed in. On the landing page there are two different arrangements of language selection. The first is in the top right corner the second is in the bottom left hand corner:
When clicking on the language in the top right hand corner the user is shown a pop-up where they can choose which language they would like to use the website in.
Changing the language of the website does not influence results returned after a search. However, when the language of the website is used in tandem with the language filtering feature introduced in the release notes for version 1.34 the user can have a full experience of using the website completely in Spanish.
Our help center has also been translated for easier use by our Spanish speaking users.
oaFindr now supported on Linux OS
Previously oaFindr could not be used on Linux based computers however this has been fixed with the most recent update.
Release 34 introduces several major language features to oaFindr
Language Filtering in Facets
Due to popular demand, 1science has launched the Language Filtering feature which provides users the ability to refine and increase the relevancy of their results based on the language of the article. This will make it easier for users to find the resources they need.
When a user performs a search they can choose to filter their results with the language option by
1. Clicking on the ‘Languages’ facet in the left hand side bar
2. Selecting preferred language
The initial view of the language facet will list the top 2 language results and display the number of articles found where the language is Undetermined.
(We are a step ahead: our team is already working on further identifying the language of articles that are currently undetermined).
Once the user clicks on ‘+ All languages’ a full list of retrieved articles in the remaining languages will be shown in alphabetical order.
Users will now be able to select multiple languages so that they are only shown results in those particular languages.
Language Filtering in Advanced Search
With the addition of language filtering on the Search Engine Result Page (SERP), users can now also search by language on the Advanced Search page. Here, users can pre-select what languages they want results to appear in. 6 Enhancements
The left hand side of the results page has seen some minor changes. Along with the addition of Language to the filtering options, Years has been moved to the top, as it is a more useful filtering option than Subjects.
Release 30 introduces several new features to oaFindr to increase accessibility and the user interface.
Cite / reference Copy-Paste
Save time citing references with the new cite / reference copy paste feature. The reference style is displayed in a Chicago Manual of Style 16th edition. To copy and paste references, follow these steps
1. Select the … symbol
2. A drop down menu will appear, Select Cite
3. A window will appear with the citation in the Chicago Manual of Style
4. Simply copy the citation and paste with the rest of your references
Data Change Request
We try to be perfect and get everything right but sometimes some mistakes can slip through. If you stumble on erroneous metadata or information that seems bizarre to you, you are now able to report these issues. Simply click on “Report” and fill out our form.
We have enhanced the look and feel of the platform with home, headers, footers, facets, revision buttons and introduced a minimalistic design with emphasis on ease of use in order to improve the functionality of the platform.
Sorting facets are now expanded by default
We added the option to sort by “Oldest article on top”
To discover this new enhancement, find it below the sorting facets on the left-hand side.
The Advanced Search has now been optimized to support combined searches and repaired language operators Improvements include:
Boolean expression in the search fields
Topics and dates are isolated from the construction of the request
Always visible Search button
