A deterministic, LLM-free screening method that uses regular expression
matching on work titles and abstracts. Works matching any include_terms
(case-insensitive) and none of the exclude_terms are classified as
"include"; works matching an exclude term are "exclude"; works
matching no include term are "exclude".
Usage
sm_screen_regex(
corpus,
include_terms,
exclude_terms = NULL,
call = rlang::caller_env()
)
