termFreq now available for treatments fulltext

[punkish]

there is a new feature in Zenodeo now… offering term frequency for treatments text. This works for single words against treatments, and has to be requested explicitly. See examples below

• https://test.zenodeo.org/v3/treatments?q=formica&termFreq=true
• https://test.zenodeo.org/v3/treatments?q=linnaeus&termFreq=true

So what can one do with this? Check out the new term frequency chart on Ocellus. If a single word is used in the search box, a fulltext search is performed, and along with the images, a term frequency chart also pops up showing the number of times that term occurred per year in treatment texts, and how many of those had images.
