Search preprint data
Usage
mx_search(
data = NULL,
query = NULL,
fields = c("title", "abstract", "authors", "category", "doi"),
from_date = NULL,
to_date = NULL,
auto_caps = FALSE,
NOT = "",
deduplicate = TRUE,
report = FALSE
)Arguments
- data
The preprint dataset that is to be searched, created either using mx_api_content() or mx_snapshot()
- query
Character string, vector or list
- fields
Fields of the database to search - default is Title, Abstract, Authors, Category, and DOI.
- from_date
Defines earliest date of interest. Written in the format "YYYY-MM-DD". Note, records published on the date specified will also be returned.
- to_date
Defines latest date of interest. Written in the format "YYYY-MM-DD". Note, records published on the date specified will also be returned.
- auto_caps
As the search is case sensitive, this logical specifies whether the search should automatically allow for differing capitalisation of search terms. For example, when TRUE, a search for "dementia" would find both "dementia" but also "Dementia". Note, that if your term is multi-word (e.g. "systematic review"), only the first word is automatically capitalised (e.g your search will find both "systematic review" and "Systematic review" but won't find "Systematic Review". Note that this option will format terms in the query and NOT arguments (if applicable).
- NOT
Vector of regular expressions to exclude from the search. Default is "".
- deduplicate
Logical. Only return the most recent version of a record. Default is TRUE.
- report
Logical. Run mx_reporter. Default is FALSE.
