Description

A searcher for use with the collation_search() algorithm. This searcher uses the Boyer-Moore matching algorithm.

`boyer_moore_collation_searcher` public construct/copy/destruct

boyer_moore_collation_searcher(I pattern_first, S pattern_last, 
                               BreakFunc break_fn, 
                               collation_table const & table, 
                               collation_strength strength = collation_strength::tertiary, 
                               case_level case_lvl = case_level::off, 
                               variable_weighting weighting = variable_weighting::non_ignorable);

Constructs a boyer_moore_collation_searcher from: a sequence of code points to find; a break function to use to determine which code points are acceptable match boundaries; and a collation table with collation configuration settings. Consider using make_boyer_moore_collation_searcher() instead of using this constructor directly.

`boyer_moore_collation_searcher` public member functions

```
template<code_point_iter I2, std::sentinel_for< I2 > S2> 
  utf32_view< I2 > operator()(I2 first, S2 last) const;
```
Returns a code point range indicating the matching subsequence within [first, last) in which this searcher's pattern was found. The range will be empty if no match exists.
