Drowning in the unfathomable results lists from PubMed? Find relevant facts, not just long lists of documents, through intelligent, easy-to-use, semantic-based queries of the biomedical literature.

Find true relationships, not simple co-occurrences: On Quertle, if you search for two or more terms, you will find documents in which those terms occur in a conceptual relationship, not simply scattered within the same document.

Quertle understands biology and chemistry: Quertle understands the difference between "TWIST", the helix-loop-helix transcription factor, and "twist", the verb. Or try a search for NO (nitric oxide).

Power Terms™ enable you to query for categories of objects: Use Power Terms™ to query for categories of objects, such as any protein or chemical (not simply the occurrence of the terms).

Easy-to-use: Quertle provides a simple, yet powerful interface that includes easy filtering and breadcrumb tracking and automatic identification of key concepts that you can click on to immediately limit the results.

Quertle’s content includes all of MEDLINE® and an increasing number of full-text articles.
