当我尝试在Lucene中搜索诸如"workaround/fix"之类的内容时,会抛出此错误:
org.apache.lucene.queryparser.classic.ParseException: Cannot parse 'workaround/fix': Lexical error at line 1, column 15. Encountered: <EOF> after : "/fix"

这是我的第111和112行:
QueryParser parser = new QueryParser(Version.LUCENE_43, field, analyzer);
Query query = parser.parse(newLine);
我需要做什么才能让它解析"/"？
Lucene 4.3.1荧光笔是如何工作的？我想从文档打印出搜索结果(作为搜索的单词和该单词后面的8个单词).我如何使用荧光笔类来做到这一点？我已将完整的txt,html和xml文档添加到文件中并将其添加到我的索引中,现在我有一个搜索公式,我可能会从中添加荧光笔功能:
String index = "index";
String field = "contents";
String queries = null;
int repeat = 1;
boolean raw = true; //not sure what raw really does???
String queryString = null; //keep null, prompt user later for it
int hitsPerPage = 10; //leave it at 10, go from there later
//need to add all files to same directory
index = "C:\\Users\\plib\\Documents\\index";
repeat = 4;
IndexReader reader = DirectoryReader.open(FSDirectory.open(new File(index)));
IndexSearcher searcher = new IndexSearcher(reader);
Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_43); …
