Question

我正在尝试使用solr-node模块在node.js中使用构面搜索来搜索在solr 6.6.5上建立索引的文档。但是当我添加facet = on＆facet.query =时：我从solr-node收到HTTP 400响应。

var client = new SolrNode({
    host: 'localhost',
    port: '8983',
    core: 'IRF18P4',
    protocol: 'http',
    debugLevel: 'ERROR' // log4js debug level paramter
});

var delhiCount = client.query.q('*:*&facet.query=city:delhi&facet=on');

// Search documents using strQuery
client.search(delhiCount, function (err, result) {
    if (err) {
       console.log(err);
       return;
    }
    console.log('Response:', result.response);
 });

但是，如果我尝试打开终端上打印的相同URL，它将起作用。对这里可能出什么问题有任何想法吗？

您在输出中打印的URL错误。

http://localhost:8983/solr/IRF18P4/select?q=*%3A*%26facet%3Don%26facet.query%3Dcity%3Adelhi&wt=json

上面应该看起来像

http://localhost:8983/solr/IRF18P4/select?q=*:*&facet=on&facet.query=city:delhi&wt=json

您的代码应该是

var delhiCount = client.query
    .q('*:*') 
    .addParams({
         facet: 'true',
         facet.query: "city:delhi"
         wt: 'json',
     });
