Solr edismax查询语法错误 "Query Field '_text _' is not a valid field name"

Question

我最初在 solr 架构中创建了 3 个复制字段:

curl -X POST -H 'Content-type:application/json' --data-binary '{"add-copy-field": {"source":"company_name","dest":"_text_"}}' http://my-instance/solr/listing/schema
curl -X POST -H 'Content-type:application/json' --data-binary '{"add-copy-field": {"source":"address","dest":"_text_"}}' http://my-instance/solr/listing/schema
curl -X POST -H 'Content-type:application/json' --data-binary '{"add-copy-field": {"source":"city","dest":"_text_"}}' http://my-instance/solr/listing/schema

但是，我最近从架构中删除了它们，现在以稍微不同的格式编写查询。更高级的查询我们需要edismax。

但是，即使打开 edismax，我也会收到来自 solr 查询解析器的错误，如下所示。我删除复制字段是否破坏了某些内容？

/solr/listing/select?debugQuery=on&defType=edismax&q=%3A&stopwords=true

{
"responseHeader": {
"zkConnected": true,
"status": 400,
"QTime": 1,
"params": {
"q": "*:*",
"defType": "edismax",
"debugQuery": "on",
"stopwords": "true"
}
},
"error": {
"metadata": [
"error-class",
"org.apache.solr.common.SolrException",
"root-error-class",
"org.apache.solr.common.SolrException"
],
"msg": "org.apache.solr.search.SyntaxError: Query Field '_text_' is not a valid field name",
"code": 400
}
}

根据评论，“文本”字段保留在配置中的 3 个位置:

"/update/extract":{
    "startup":"lazy",
    "name":"/update/extract",
    "class":"solr.extraction.ExtractingRequestHandler",
    "defaults":{
      "lowernames":"true",
      "fmap.content":"_text_"}}


"spellchecker":{
      "name":"default",
      "field":"_text_",


"initParams":[{
    "path":"/update/**,/query,/select,/tvrh,/elevate,/spell,/browse",
    "defaults":{"df":"_text_"}}]

Answer 1

根据对我的问题的评论(我仍在 solr 的学习道路上):

Although they have been deprecated for quite some time, Solr still has support for Schema based configuration of a <defaultSearchField/> (which is superseded by the df parameter) and <solrQueryParser defaultOperator="OR"/> (which is superseded by the q.op parameter.

If you have these options specified in your Schema, you are strongly encouraged to replace them with request parameters (or request parameter defaults) as support for them may be removed from future Solr release.

出于我们的目的，当我们使用 edismax 查询解析器时，我们需要指定我们想要使用的查询字段。
