In the last few days I am always getting a 400 when calling the Evaluate API via POST.
In the last few days (4 days) I am getting a 400 when calling the Evaluate API (rest) via POST.
The response is always :

"Code": "System.AggregateException",
"Message": "One or more errors occurred.",

Extended metadata keeps being added and removed.
A month ago, if I made this request:
params = {'expr': 'Composite(AA.AuId=120559464)', 'attributes': 'Id,E.DN'}
I'd get back:
{
'logprob': -19.012,
'prob': 5.5359647e-09,
'Id': 2036161137,
'DN': 'Extracellular vesicles as drug delivery systems : lessons from the liposome field',
'PK': 2036161137}
Now, the Display Name (DN) is missing. This is not the first time metadata has gone missing; it was AWOL in February and March as well. See https://github.com/MicrosoftDocs/azure-docs/issues/24799
Will this be fixed?

When searching for an AuN in evaluate, doubling single quote does not work for people with apostrophes - it returns an error. This is a huge problem for us - is there a workaround?

What is the throttling limit of per preview key?
Thanks very much for providing this service, but I really want to know some critical information such as how many quest per second/minute, how many quest per day/week/month, or is there a limit of total response size?
Please also note these information in document, thanks.

Support querying by DOI
Right now, since DOIs only exist in the extended metadata, it is impossible to query the Academic Knowledge API by DOI - to do things like obtain paper citation counts, it is necessary to first obtain the Microsoft Academic paper ID.
I would like to be able to query by DOI, to make it easier to integrate Academic Knowledge into systems that track papers generally. For a use case, I am using Academic to drive the citation counts in my publication list at https://md.ekstrandom.net/pubs/, and would like to have my query code automatically pick up papers by DOI as…

"String Attribute: Prefix value" query isn't working
The following queries shown in the documentation (https://docs.microsoft.com/en-us/azure/cognitive-services/academic-knowledge/queryexpressionsyntax) do not work:
Ti='indexing by latent seman'...
Composite(AA.AuN='sue du'...)However the numeric version does work:
Y='19'...
Being able to query strings via a prefix value would be really useful.

We should be able to query by Entity Type (i.e. 'book', 'paper', etc.)
In the Evaluate API endpoint, we should be able to query based on Entity Type
i.e. the following API call:
https://api.labs.cognitive.microsoft.com/academic/v1.0/evaluate?expr=Composite(Ty=0)should return results which are 'book's

Can you provide updates to users when the api's change?
After the 500 errors last week, my script is no longer returning results. It seems the api changed from right under me. I wish I had been notified. I paid for support, but they has been of little help. Can you communicate changes to the API?

Searching publications should take word sequence into consideration
I am interested in finding papers that quote exactly the text "Ecopath with Ecosim", not papers that contain the words 'Ecosim' and 'with' and 'Ecosim' because that may return irrelevant publications.
IE - specific titles.

Query evaluate by exact ID
In the Evaluate API endpoint, we should be able to query based on Entity Type
i.e. the following API call:
https://api.labs.cognitive.microsoft.com/academic/v1.0/evaluate?expr=Id=1500058340should return the entity 1500058340

Repeating AffiliationIDs
In the "Author" entity, List<uint> AffiliationID can contain many duplicates. This dramatically slows down query time.
From the example query below you can immediately see the Entity ID '1341412227' being repeated over 30 times--ridiculous.
{"path": "/author",
"author": {
"type": "Author",
"match": {"DisplayAuthorName": "Chiao-Fe Shu"},
"select": [ "DisplayAuthorName", "AffiliationIDs" ],
"return": {}
}}

How do I use Academic API with DreamSpark?

Academic search results
It seems that for some searches on Microsoft academic API (and Microsoft's own web portal), the top result (in terms of relevance and citations count) is absent.
For example, search for "topological insulators". The top result, correctly given by Google scholar, is the most cited review article in the field, from 2010 (7454 citations), titled Colloquium: topological insulators.
In Microsoft's academic however, there is no mention of this seminal article no matter if you order results by relevance or by citations.
How can that be?
