SOLR查询逗号分隔的字段，无顺序

问题描述

我有一个字段，其中包含逗号分隔的值，例如JSON，AngularJS，另一个字段为AngularJS，JSON，而其他字段仅包含JSON，HTML.

I have a field which has comma separated values for e.g JSON,AngularJS and another as AngularJS,JSON and other having JSON,HTML only.

现在我一直在尝试使用fq = field:( JSON AngularJS *)查询SOLR，但是它只返回AngularJS之前带有JSON的记录.

Now i have been trying to query SOLR using fq=field:(JSONAngularJS*), but it returns only the record with JSON before AngularJS.

我如何查询SOLR，以便它返回具有JSON和AngularJS但不考虑顺序的记录.

How can i query SOLR so that it returns both the records having JSON and AngularJS but not considering the order.

为该字段附加SOLR分析:

查询形式: http://localhost:8983/solr/my_core/select?fq = field:(JSON％20AND％20AngularJS)& q = :

推荐答案

使用基于,进行标记化的字段类型(即，列表中的每个条目都产生一个单独的标记).您可以使用 SimplifiedRegularExpressionPatternTokenizer :

Use a field type that is tokenized based on , (i.e. each entry in your list results in a separate token). You can do this by using a SimplifiedRegularExpressionPatternTokenizer:

<fieldType name="text" class="solr.TextField">
  <analyzer>
    <tokenizer class="solr.SimplePatternTokenizerFactory" pattern="[^,]+"/>
  </analyzer>
</fieldType>

通过查询两个令牌都存在的文档来查询索引.

Query the index by asking for documents having both tokens present fq=field:(JSON AND AngularJS).

(问题更新后)

首先-您的字段似乎是 string 字段，而不是TextField.

First - your field seems to be a string field, and not a TextField.

要通过API添加具有正确定义的字段:

To add a field through the API with the correct definition:

curl -X POST -H 'Content-type:application/json' --data-binary '{
  "add-field-type" : {
     "name":"comma-separated-list",
     "class":"solr.TextField",
     "positionIncrementGap":"100",
     "analyzer" : {
        "tokenizer":{
           "class":"solr.SimplePatternTokenizerFactory", "pattern": "[^,]+" },
        }
     }
  }
}' http://localhost:8983/solr/collectionname/schema

添加一组示例文档后:

[
      {
        "langs":"JSON,AngularJS,Microsoft Visual Basic",
        "id":"foo",
        "address":"None",
        "_version_":1606953238273196032},
      {
        "langs":"JSON,AngularJS",
        "id":"foo2",
        "address":"None",
        "_version_":1606953238277390336},
      {
        "langs":"JSON,Microsoft Visual Basic",
        "id":"foo3",
        "address":"None",
        "_version_":1606953238278438912},
      {
        "langs":"AngularJS,JSON",
        "id":"foo4",
        "address":"None",
        "_version_":1606953238278438913}]

然后使用fq=langs:(JSON AND AngularJS)&q=*:*)查询:

  {
    "langs":"JSON,AngularJS,Microsoft Visual Basic",
    "id":"foo",
    "address":"None",
    "_version_":1606953238273196032},
  {
    "langs":"JSON,AngularJS",
    "id":"foo2",
    "address":"None",
    "_version_":1606953238277390336},
  {
    "langs":"AngularJS,JSON",
    "id":"foo4",
    "address":"None",
    "_version_":1606953238278438913}]

未定义AngularJS的文档已被删除.

The document that didn't have AngularJS defined has been left out.
