Java 没有为使用Lucene 4.1的CharMappingFilter的分析器获取匹配项

只是将代码库从Lucene 3.6更新到Lucene 4.1，似乎我使用NormalizeCharMap替换分析器中的字符的测试不起作用

下面我创建了一个独立的测试用例，这是我运行它时的输出

--term=and--
--term=gold--
--term=platinum--
name:"platinum and gold"
Size1
name:"platinum & gold"
Size0

java.lang.AssertionError:

不太确定，但我想询问者做的不仅仅是分析……”“例如”是一个特殊的关键字。您可能遇到了一个有趣的边缘情况：）

4.1中还有更多的QueryParser实现。。。例如，请参见

我发现了一个问题，我必须重写新的initReader（）方法，以便在analyzer与QueryParser一起使用时应用它。不确定是否也需要在createComponents（）中构造过滤器，但如果我只添加到initReader，则测试是否有效

class SimpleAnalyzer extends Analyzer {

        protected NormalizeCharMap charConvertMap;

        protected void setCharConvertMap() {

            NormalizeCharMap.Builder builder = new NormalizeCharMap.Builder();
            builder.add("&","and");
            charConvertMap = builder.build();
        }

        public SimpleAnalyzer() {
            setCharConvertMap();
        }

        @Override
        protected TokenStreamComponents createComponents(String fieldName, Reader reader) {
            Tokenizer source = new MusicbrainzTokenizer(Version.LUCENE_35,
                    reader);
            TokenStream filter = new LowerCaseFilter(Version.LUCENE_35,source);
            return new TokenStreamComponents(source, filter);
        }

        @Override
        protected Reader initReader(String fieldName,
                                    Reader reader)
        {
            return new MappingCharFilter(charConvertMap, reader);
        }
    }

Thx，但我只是尝试从Lucene 3.6更新到Lucene.4.1，而不重写大部分代码。

class SimpleAnalyzer extends Analyzer {

        protected NormalizeCharMap charConvertMap;

        protected void setCharConvertMap() {

            NormalizeCharMap.Builder builder = new NormalizeCharMap.Builder();
            builder.add("&","and");
            charConvertMap = builder.build();
        }

        public SimpleAnalyzer() {
            setCharConvertMap();
        }

        @Override
        protected TokenStreamComponents createComponents(String fieldName, Reader reader) {
            Tokenizer source = new MusicbrainzTokenizer(Version.LUCENE_35,
                    reader);
            TokenStream filter = new LowerCaseFilter(Version.LUCENE_35,source);
            return new TokenStreamComponents(source, filter);
        }

        @Override
        protected Reader initReader(String fieldName,
                                    Reader reader)
        {
            return new MappingCharFilter(charConvertMap, reader);
        }
    }
