stri_*_coll
functions in stringi utilize
ICU's StringSearch
engine --
which implements a locale-sensitive string search algorithm.
The matches are defined by using the notion of ``canonical equivalence''
between strings. Tuning the Collator's parameters allows you to perform correct matching
that properly takes into account accented letters, conjoined letters,
ignorable punctuation and letter case. For more information on ICU's Collator and the search engine
and how to tune it up
in stringi, refer to stri_opts_collator
. Please note that ICU's StringSearch
-based functions
often exhibit poor performance. These functions are not intended to
be fast; they are made to give correct in natural
language processing tasks.L. Werner, Efficient Text Searching in Java, 1999, http://icu-project.org/docs/papers/efficient_text_searching_in_java.html
