OpenAPI specification document for Intelligent X Search API

[Azuris2]

I've just uploaded the OpenAPI docs for the search API. I cleaned up some of the text and made some edits based on my testing with the API. For some of the details such as the license limitations and the User-Agent header, I've left them out to avoid bloating the doc, but if its beneficial, I could include them instead.

Some issues I had (some are left as a comment on the file):

• Intelligent/search endpoint - returns altterm and altermh that wasn't specified in the docs. I'm not sure if this was due to a recent change, or due to an upgrade of my API key. For the dates, I'm not too sure what the format should be so I've listed them as a string. (It wouldn't throw up an error for incorrect dates)
• Intelligent/search/result endpoint - returns a few key-value pairs that were not defined in the API docs. Also, in my testing, the "type" gave me a value of 1006 that was not defined in the API docs.
• Phonebook/search/result endpoint - I originally referenced the intelligent/search/result response for this, but I realised that the actual response is quite different from the initial documentation and they were not defined. E.g. selectors, selectortype. Would need to be re-documented if that's indeed the case.
• For the file/preview endpoints, I wasn't able to test it as I'm not sure how some of the parameters were defined (along with their available values).
• I've left some key-value pairs/parameters blank as I wasn't too clear on what their definition/values were.
• Lastly, I noticed that some parameters have the same definition/values but they are named differently. Just something to keep in mind as they have to be defined separately in the spec. E.g. systemid vs sid

I would be happy to keep working on the documentation if you have any feedback.

Cheers!
