我正在使用 Jquery 对这些数据进行搜索，如下所示：
function on_data(data)
$('#results').empty();
var docs = data.response.docs;
$.each(docs, function(i, item)
$('#results').prepend($('<div>' + item.name + '</div>'));
);
var total = 'Found ' + docs.length + ' results';
$('#results').prepend('<div>' + total + '</div>');
function on_search()
var query = $('#query').val();
var url = 'http://localhost:8983/solr/techs/select?q=' + query + '&start=0&rows=10&indent=on&wt=json&callback=?&json.wrf=on_data';
$.getJSON(url);
function on_ready()
$('#search').click(on_search);
/* Hook enter to search */
$('body').keypress(function(e)
if (e.keyCode == '13')
on_search();
);
$(document).ready(on_ready);
但我没有收到任何响应，因为 URL“http://localhost:8983/solr/techs/select?q=Rick&start=0&rows=4&indent=on&wt=json&callback=?&json.wrf=on_data”返回以下内容：
on_data(
"responseHeader":
"status":0,
"QTime":68,
"params":
"q":"Rick",
"json.wrf":"on_data",
"indent":"on",
"start":"0",
"callback":"?",
"rows":"4",
"wt":"json",
"response":"numFound":0,"start":0,"maxScore":0.0,"docs":[]
,
"highlighting":)
但如果我使用此 URL 搜索：“http://localhost:8983/solr/techs/select?q=&start=0&rows=4&indent=on&wt=json&callback=?&json.wrf=on_data”，我会得到如下正确响应：
on_data(

"q":"",
"json.wrf":"on_data",
"indent":"on",
"start":"0",
"callback":"?",

我相信这是因为值中的空格，即“Rick Riordan”。在这种情况下，有人可以帮助我更正我的 Jquery 代码/SOLR 配置。我是 SOLR 的新手。我也想在搜索框上实现自动完成。你能帮我解决一下吗？
提前致谢！
【问题讨论】：
您的查询中没有字段，例如q=author:"Rick*" 那么您是否在 schema.xml 中定义了默认搜索字段，您是否将作者索引到该字段中？ 查看***.com/questions/5449727/… 示例 实际上我不想在查询中包含硬编码字段，因为我想使用多个字段进行搜索。有时按作者，有时按名称或流派。我查看了您分享的示例。试试看，谢谢！ 我尝试了您建议的示例，不幸的是我没有得到搜索结果 :( 我在托管模式中添加了一个名为“text”的默认字段，并且我的所有字段都有 copyField 条目。并且我将“文本”传递到 SOLR Admin 中的“df”字段并运行 URL：“localhost:8983/solr/techs/select?df=text&q=*Rick*&start=0&rows=10&indent=on&wt=json&callback=?&json.wrf=on_data”.. 我做错什么了吗? 【参考方案1】：我终于找到了我的问题的答案！不需要在查询中指定字段名称，例如“例如 q=author:“Rick*””。 SOLR 可以对我们在 solrconfig.xml 中的 DisMax 参数“qf”下指定的字段的值执行搜索。如下所示：
<requestHandler name="/select" class="solr.SearchHandler">
<!-- default values for query parameters can be specified, these
will be overridden by parameters in the request
-->
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<!-- Query settings -->
<str name="defType">edismax</str>
<str name="qf">
author name pages price genre_s
</str>
<str name="df">*_str</str>
<str name="mm">100%</str>
<str name="q.alt">*:*</str>
<str name="rows">10</str>
<str name="fl">*,score</str>
</lst>
</requestHandler>
现在，如果我使用 URL "http://localhost:8983/solr/techs/select?q=rick" OR "http://localhost:8983/solr/techs/select?q='Rick'&start=0&rows=4&indent=on&wt=json&callback=?&json.wrf=on_data" 进行搜索，我得到以下回复：
"responseHeader":
"status":0,
"QTime":8,
"params":
"q":"rick",
"response":"numFound":2,"start":0,"maxScore":0.6931472,"docs":[
