Filter articles from a specific data or date range

[BryanTegomoh]

I can't find an option to filter articles within a date range. An argument possibly within epmc_search() function to narrow down to a date range. Additionally, can we curate all the articles within that range instead of defining a limit?

Hi @BryanTegomoh Please apologize my late reply. You could make use of the extensive Europe PMC search syntax to narrow down results to a specific date range. Europe PMC provides a great query builder.

Example: Publications about "SARS-CoV-2" published between 2023-09-01 and 2023-09-11.

library(europepmc)
epmc_search('(FIRST_PDATE:[2023-09-01 TO 2023-09-11]) AND "SARS-CoV-2"')
