帮我优化这段代码：List<TextSegment> matches = new ArrayList<>(); PositionInParagraph startPosition = new PositionInParagraph(); TextSegment match = xwpfParagraph.searchText(entry.getKey(), startPosition); while (match != null) { startPosition = new PositionInParagraph(match, false); // update start position to the end of current match matches.add(match); match = xwpfParagraph.searchText(entry.getKey(), startPosition); } TextSegment textSegement = xwpfParagraph.searchText(entry.getKey(), new PositionInParagraph());

可以将循环中的代码提取为方法，避免重复。同时，可以使用 foreach 循环遍历要搜索的文本列表，减少代码量。优化后的代码如下：

List<TextSegment> matches = new ArrayList<>();
PositionInParagraph startPosition = new PositionInParagraph();

for (String searchText : searchList) {
    TextSegment match = xwpfParagraph.searchText(searchText, startPosition);
    while (match != null) {
        startPosition = new PositionInParagraph(match, false); // update start position to the end of current match
        matches.add(match);
        match = xwpfParagraph.searchText(searchText, startPosition);
    }
    startPosition = new PositionInParagraph();
}

这样，代码就更简洁了，同时也更易于阅读和维护。需要注意的是，`searchList` 是一个包含要搜索的文本列表的字符串数组，你需要将其定义并初始化。
