Question

问题：当我上传word文档时，我可以搜索标题（在上传文档时输入）和摘要，但是当我使用文档中的某些文本进行搜索时，我得到了结果。

我正在使用＆＃34; hibernate-search-engine：4.3.0.Final，lucene-core：3.6.2＆＃34;

的pom.xml

        SitePageContent sitCont = (SitePageContent) value;
        Content cont = sitCont.getContent();
        UploadedFile upF = cont.getUploadedFile();
        if (upF != null) {
            String fieldValue1 = upF.getFileContentType();
            if ( fieldValue1 == null ) {
                fieldValue1 = "";
            }
            byte[] fieldValue2 = upF.getFileContent();
            if ( fieldValue2 == null ) {
                fieldValue2 = new byte[0];
            }
            fieldValue = convertFile2String(fieldValue1, fieldValue2);
        } else {
            fieldValue = "";
        }
        Field field = new Field( name, fieldValue, luceneOptions.getStore(), luceneOptions.getIndex(), luceneOptions.getTermVector() );
        field.setBoost( luceneOptions.getBoost() );
        document.add( field );
    }



    private String convertFile2String(String type, byte[] content) {
  }

当我调试＆＃34; WordDocHandlerBridge.java＆＃34;时，我能够看到我的内容在Field中设置并添加到文档中，但是当我搜索时我没有得到它。

注意：有一个standolne程序为我重新创建索引，如果我重新创建，我可以看到结果。

任何人都可以帮我解决这个问题。

Answer 1

我解决了这个问题，WordDocHandlerBridge中的这个类＆＃34; convertFile2String＆＃34;，实际打开文件并读取文件并创建一个String来设置Field中的值，问题是Code没有关闭＆＃ 34;文件＆＃34;还有一些Luecene没有更新，但是当我加入PDF和POI文件时，它们都开始工作了。

这里指出它曾经与Luecene 2.4一起使用，这可能是Lucene 3.6中的新功能，这是一个很好的功能。

文档上的Lucene索引不能通过ClassBridge钩子工作
