Operators lie at the heart of Tattle Search. Operators define ways in which you can manipulate data that your search engine wants to operate on. You can configure Tattle Search to load as many or as few operators at runtime. Your modules can then access the configured operators by its key and use it by invoking its run method.
text_vec = operators["text_vec_rep_paraphrase_lxml"].run(text)
image_vec = operators["image_vec_rep_resnet"].run(image)
To create your own operators, make a class with the interface :
Use one of the existing operators as guide. detect_text_in_image is a fairly simple one.
If you wish to add your operator to Tattle Search, please make a PR with your operator and test for it. In the future we may consider a plugin architecture to allow Tattle Search to enable third party operators.
It is essential to include working tests in your operator code. Please ensure your test demonstrates all ways in which the operator can be used. This serves as documentation for anyone who wishes to use it in their code.
