+ * <tt>SearchIterator</tt> is an abstract base class that provides
+ * methods to search for a pattern within a text string. Instances of
+ * <tt>SearchIterator</tt> maintain a current position and scans over the
+ * target text, returning the indices the pattern is matched and the length
+ * of each match.
+ * <p>
+ * <tt>SearchIterator</tt> defines a protocol for text searching.
+ * Subclasses provide concrete implementations of various search algorithms.
+ * For example, <tt>StringSearch</tt> implements language-sensitive pattern
+ * matching based on the comparison rules defined in a
+ * <tt>RuleBasedCollator</tt> object.
+ * <p>
+ * Other options for searching includes using a BreakIterator to restrict
+ * the points at which matches are detected.
+ * <p>
+ * <tt>SearchIterator</tt> provides an API that is similar to that of
+ * other text iteration classes such as <tt>BreakIterator</tt>. Using
+ * this class, it is easy to scan through text looking for all occurances of
+ * a given pattern. The following example uses a <tt>StringSearch</tt>
+ * object to find all instances of "fox" in the target string. Any other
+ * subclass of <tt>SearchIterator</tt> can be used in an identical
+ * manner.
+ * <pre><code>
+ * UnicodeString target("The quick brown fox jumped over the lazy fox");
+ * UnicodeString pattern("fox");
+ *
+ * SearchIterator *iter = new StringSearch(pattern, target);
+ * UErrorCode error = U_ZERO_ERROR;
+ * for (int pos = iter->first(error); pos != USEARCH_DONE;
+ * pos = iter->next(error)) {
+ * printf("Found match at %d pos, length is %d\n", pos,
+ * iter.getMatchLength());
+ * }
+ * </code></pre>
