Free PubMed Alternative

Frustrated with PubMed?

Getting lost in overwhelming lists of documents?

Want more content, including full-text?

Finding it hard to use?

Although PubMed is a tremendous resource, it clearly has some major shortcomings. There are several alternatives available, but they all search using simple keyword matching and find many irrelevant results. In fact, most PubMed alternatives use PubMed's search engine and just add their own interface. And some are even harder to use than PubMed!

Don't you want a PubMed alternative that is smarter, covers more content, is easier to use - yet is still free? Introducing Quertle.

Advanced Linguistic Methods Find Relevant Results - Quertle searches for facts asserted by the author, not just the occurrence of your search terms anywhere in the document. Simply enter the concept you are searching for, and Quertle will dissect the sentences to find the relevant articles. This generally provides a shorter, but more relevant, list of results than PubMed. No need for complicated Boolean expressions as needed on PubMed or any of the other alternatives. You spend less time wading through the results and more time being productive.

Automatic searching for all aliases and synonyms - Quertle automatically looks for all variations of your gene, disease, chemical, etc. You don't have to enter awkward Boolean queries such as "valium or diazepam or 439-14-5 or relanium or novazam or ...". You get to the right papers, right away.

A single search for all members of a category - Quertle's Power Terms allow you to search for all proteins, all chemicals, etc. in a single query. For example, $Diseases represents all diseases - not the word disease. So, a search such as ethanol causes what $Diseases will find articles about ethanol causing specific diseases, and you get a list of those diseases. You can't do that on PubMed or any other alternative sites. You get real answers to real questions.

One Search Covers Multiple Sources - Quertle searches all of PubMed, NIH grant applications, TOXLINE, whitepapers, and news. You find everything that is relevant in a single search.

Full-text Searching - Quertle searches an expanding collection of full-text articles, so you find documents that contain relevant information in the Materials and Methods, etc. PubMed only searches the title and abstract. And, unlike other full-text search engines such as Highwire or Google Scholar, Quertle is smart enough not to search inside the references. You find the important facts from all informative sections of the full text.

Simple Filters to Drill Down - Right on the Results Page - Quertle provides easy-to-use filters so you can quickly hone in on what is most important. No need to go to a separate, complicated Limits page as on PubMed. Quertle also automatically identifies key concepts in the documents and provides that list as another filter. You can drill down to the documents you want very quickly.

Highlighting - Quertle presents the relevant facts, or relationships, with your search terms highlighted. No longer do you have to go to another page to see the abstract and even then wonder why that article was found. You know exactly why the document is relevant.

Links for Access to the Documents - Quertle provides links to many Open Access documents. Plus, a link is available to access other full-text documents through your library's subscriptions, with more than 1300 organizations supported. (Don't see your library listed? No problem, just send us a free request.) You have easy access to the full-text documents.
