Get more than 25 articles from ISSN

[Belzun]

When I execute
x <- generic_elsevier_api(query = "ISSN(0004-3702) AND YEAR(2001)", search_type = "scopus") x$content$search-results$opensearch:totalResults``
I get 66 as results obtained, but I can't see more than 25, that are the first page. How can I get all the results?

Thanks for this package!!

You have to loop over the next query yourself. I don’t remember where but it is in the result

I am not able to see more than 25 results. I have tried adding more information to my query, such as COUNT(1), or PAGE(1) and similar things, but nothing worked.

[muschellij2]

You need to call the next call to the api yourself. The count is maxed out at 25

So this package won't help me getting more than 25 results?

[muschellij2]

Not currently.

This will get you started.

devtools::install_github("muschellij2/rscopus")
x <- generic_elsevier_api(
query = "ISSN(0004-3702) AND YEAR(2001)", 
search_type = "scopus")
x$content$`search-results`$`opensearch:totalResults`

[1] "66"

xx = get_next(x)
length(xx$content$`search-results`$entry)

[1] 25

xxx = get_next(xx)
length(xxx$content$`search-results`$entry)

[Belzun]

Thank you very much for this.
The first get_next() works fine, but the second get_next() and the following ones don't work, they return the same result.
xx = get_next(x) works well.

xxx = get_next(xx) doesn't work.

[muschellij2]

What do you mean by they don’t work

If I apply get_next() to the one obtained with get_next(), I don't get the next page.
For example:
x <- generic_elsevier_api(query = "ISSN(0004-3702) AND YEAR(2001)", search_type = "scopus") It returns from 1 to 25.
xx = get_next(x) Returns 26 to 50.
xxx = get_next(xx) Returns the same as xx, from 26 to 50, not 51 to 75 (66 in this case).

[muschellij2]

This seems like an issue with their API - please provide me a link to the message you are sending to their feedback ( https://service.elsevier.com/app/overview/scopus/) Use get_last for the last set of records. Best, John

I just downloaded your package again from your github and works perfect. I don't understand why, but now it works.
So thanks a lot for your time, I really appreciate it. And thank you for this package, it makes everything easier.
