Article search problem

[happylilem]

Hi, I'm trying to use this library to obtain PubMed article attributes. The sample script works perfectly when I used it to search for the sample PubMed article “Deal or no deal? ”. However, when I tried to substitute this article with other PubMed articles, my Jupyter Notebook simply responded "None" instead of any results as it did for the sample article. I wonder if there were any restrictions on the articles that could be reached by this library. I would be very thankful if you could help me with this!

The search string that worked is:
title = "Deal or no deal? The prevalence and nutritional quality of price promotions among U.S. food and beverage purchases."
and it returns the article attributes as
OrderedDict([('doi', '10.1016/j.appet.2017.07.006'), ('title', 'Deal or no deal? The prevalence and nutritional quality of price promotions among U.S. food and beverage purchases'), ('url', 'https://europepmc.org/articles/PMC5574185/'), ('authors', ['Taillie, Lindsey Smith', 'Ng, Shu Wen', 'Xue, Ya', 'Harding, Matthew']), ('open', True)])

When I changed the string to another PubMed article such as this one:
title = "A Comparative Study of Free Oligosaccharides in the Milk of Domestic Animals"
The response is None.
I tried several other articles, and the responses were also None. The article titles didn't contain any special characters.

Here is the entire script I used, which is just the one shown as sample except that I changed the article title--
from richcontext import scholapi as rc_scholapi
schol = rc_scholapi.ScholInfraAPI(config_file="rc.cfg", logger=None)
source = schol.openaire
title = "A Comparative Study of Free Oligosaccharides in the Milk of Domestic Animals"
if source.has_credentials():
response = source.title_search(title)
if response.message:
print(response.message)
else:
print(response.meta)

Hi @happylilem,

I tested your code and I see that you are using OpenAIRE integration, instead of the intended PubMed, so if you do this on your code...

source = schol.pubmed

... you will get a result.

I realized we need to improve our documentation to make more explicit how to access each service. For now, you can see here a hint of the other options you have.
