You can pass in more than one identifier to id parameter.

Search API

This is the API for the same query interface you’d use on the DataCite website.

Search for the term laser

dc_search(q = "laser", fl = c('doi','publicationYear'), rows = 5)
#> # A tibble: 5 x 2
#>                          doi publicationYear
#>                        <chr>           <chr>
#> 1             10.7283/R3ZW26            2016
#> 2 10.17035/D.2016.0008119129            2016
#> 3             10.7283/R3V30K            2016
#> 4      10.2314/GBV:667365621            2010
#> 5      10.2314/GBV:72192168X            2012

Another search: published between 2000 and 2005

dc_search(q = "publicationYear:[2000 TO 2005]", fl = c('doi', 'publicationYear'), rows = 5)
#> # A tibble: 5 x 2
#>                   doi publicationYear
#>                 <chr>           <chr>
#> 1 10.17192/Z2003.0408            2003

#> 3        10.17617/1.6            2004
#> 4  10.17617/2.2250118            2005
