docs: instructions syntax

[greenpau]

Here is what I have noted for myself.

The syntax to write instructions: "Represent the domain text_type for task_objective: ", where:

• domain is optional, and it specifies the domain of the text, e.g., science, finance, medicine, etc.
• text_type is required, and it specifies the encoding unit, e.g., sentence, document, paragraph, etc.
• task_objective is optional, and it specifies the objective of embedding, e.g., retrieve a document, classify the sentence, etc.

The questions:

1. what is the exhaustive list of possible values for domain?
2. what is the exhaustive list of possible values for text_type?
3. what is the exhaustive list of possible values for task_objective?

Awesome work! 👍 Thank you for the models!

Hi, Thanks a lot for your interest in the INSTRUCTOR!

Although it may be hard to exhaustively list all possible values of domain, test type and task objective, we provide some examples in the table 4 of our paper.

Feel free to add more questions or comments!
