This search collator is best used at SECONDARY strength with an "asymmetric" search as described in the [<a href="https://www.unicode.org/reports/tr41/#UTS10">UCA</a>] section Asymmetric Search and obtained, for example, using ICU4C's usearch facility with attribute USEARCH_ELEMENT_COMPARISON set to value USEARCH_PATTERN_BASE_WEIGHT_IS_WILDCARD; this ensures that a full Hangul syllable in the search pattern will only match the same syllable in the searched text (instead of matching any syllable with the same initial consonant), while a Hangul initial consonant in the search pattern will match any Hangul syllable in the searched text with the same initial consonant.</td></tr>
