-/**
- * BoyerMooreSearch
- *
- * This object holds the information needed to do a Collation sensitive Boyer-Moore search. It encapulates
- * the pattern, the "bad character" and "good suffix" tables, the Collator-based data needed to compute them,
- * and a reference to the text being searched.
- *
- * To do a search, you fist need to get a <code>CollData</code> object by calling <code>CollData::open</code>.
- * Then you construct a <code>BoyerMooreSearch</code> object from the <code>CollData</code> object, the pattern
- * string and the target string. Then you call the <code>search</code> method. Here's a code sample:
- *
- * <pre>
- * void boyerMooreExample(UCollator *collator, UnicodeString *pattern, UnicodeString *target)
- * {
- * UErrorCode status = U_ZERO_ERROR;
- * CollData *collData = CollData::open(collator, status);
- *
- * if (U_FAILURE(status)) {
- * // could not create a CollData object
- * return;
- * }
- *
- * BoyerMooreSearch *search = new BoyerMooreSearch(collData, *patternString, target, status);
- *
- * if (U_FAILURE(status)) {
- * // could not create a BoyerMooreSearch object
- * CollData::close(collData);
- * return;
- * }
- *
- * int32_t offset = 0, start = -1, end = -1;
- *
- * // Find all matches
- * while (search->search(offset, start, end)) {
- * // process the match between start and end
- * ...
- * // advance past the match
- * offset = end;
- * }
- *
- * // at this point, if offset == 0, there were no matches
- * if (offset == 0) {
- * // handle the case of no matches
- * }
- *
- * delete search;
- * CollData::close(collData);
- *
- * // CollData objects are cached, so the call to
- * // CollData::close doesn't delete the object.
- * // Call this if you don't need the object any more.
- * CollData::flushCollDataCache();
- * }
- * </pre>
- *
- * NOTE: This is a technology preview. The final version of this API may not bear any resenblence to this API.
- *
- * Knows linitations:
- * 1) Backwards searching has not been implemented.
- *
- * 2) For Han and Hangul characters, this code ignores any Collation tailorings. In general,
- * this isn't a problem, but in Korean locals, at strength 1, Hangul characters are tailored
- * to be equal to Han characters with the same pronounciation. Because this code ignroes
- * tailorings, searching for a Hangul character will not find a Han character and visa-versa.
- *
- * 3) In some cases, searching for a pattern that needs to be normalized and ends
- * in a discontiguous contraction may fail. The only known cases of this are with
- * the Tibetan script. For example searching for the pattern
- * "\u0F7F\u0F80\u0F81\u0F82\u0F83\u0F84\u0F85" will fail. (This case is artificial. We've
- * been unable to find a pratical, real-world example of this failure.)
