Want to know how we did it?

 
Steps

 

  1. An example: I searched for experiments about "skin cancer". Strikingly, searching the phrase without quotation marks actually returns fewer experiments. This is due to the expansion of the complete phrase to child terms in the Experimental Factor Ontology. If I use quotation marks, my search will also find experiments mentioning the type of skin cancer "melanoma" but not the words "skin" and "cancer".
  2. To find e.g. mouse models of this disease, I selected the organism "Mus musculus" from the filter option "By organism". I also selected "Array assay" to only find array-based experiments. Adding "ef:diet" will show me experiments that have tested the effect of diet on skin cancer.
