我试图用solr索引pdf但没有成功。它是datanfig.xml中的baseDir和/或url吗？如何正确设置上述属性？当我索引pdf时，我得到以下内容： 来自Solr：

对于Tika，你需要在dist目录中使用apache-solr-dataimporthandler-extras-3.6.0。
答案 1 :(得分：1)
我已将PDF格式编入索引使用Solrj库的doc文件。以下代码段有效：
String urlString = "http://localhost:8983/solr";
SolrServer solr = null;
try {
solr = new CommonsHttpSolrServer(urlString);
} catch (MalformedURLException e2) {
e2.printStackTrace();
}
ContentStreamUpdateRequest up = new ContentStreamUpdateRequest("/update/extract");
try {
try {
up.addFile(file);
} catch (IOException e1) {
e1.printStackTrace();}
up.setParam("literal.id", solrId);
up.setParam("uprefix", "attr_");
up.setParam("fmap.content", "attr_content");
up.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
try {
solr.request(up);
} catch (IOException e) {
e.printStackTrace();
}
} catch (SolrServerException e) {
e.printStackTrace();
}
索引后，您可以查询“attr_content”（pdf文件的内容）。
