Apache Solr suggester dictionary在从集合中删除某些记录后不会更新

Question

我想在上传一些初始数据（在Solr 5.3.1中）后更新Solr suggester字典。suggester字典在删除所有数据并将修改后的数据上载回后进行更新。但是当我删除任何特定的记录（例如ID=123)时，建议者仍然在结果集中返回被删除的记录。

null

[
    {
        "id": 1,
        "name": "New York"
    },
    {
        "id": 2,
        "name": "New Jersey"
    },
    {
        "id": 3,
        "name": "California"
    }
]

curl -X POST -H 'Content-Type: application/json' 'http://localhost:8983/solr/mycollection/update?commit=true' --data-binary @json_data.json

{
    "responseHeader": {
        "status": 0,
        "QTime": 0,
        "params": {
            "q": "*:*",
            "indent": "true",
            "wt": "json",
            "_": "1448271522315"
        }
    },
    "response": {
        "numFound": 3,
        "start": 0,
        "docs": [
            {
                "id": "1",
                "name": [
                    "New York"
                ],
                "_version_": 1518622755181822000
            },
            {
                "id": "2",
                "name": [
                    "New Jersey"
                ],
                "_version_": 1518622755186016300
            },
            {
                "id": "3",
                "name": [
                    "California"
                ],
                "_version_": 1518622755187064800
            }
        ]
    }
}

{
    "responseHeader": {
        "status": 0,
        "QTime": 0
    },
    "spellcheck": {
        "suggestions": [
            "New",
            {
                "numFound": 2,
                "startOffset": 0,
                "endOffset": 3,
                "suggestion": [
                    "New Jersey",
                    "New York"
                ]
            }
        ],
        "collations": [
            "collation",
            "(New Jersey)"
        ]
    }
}

现在我使用以下命令从mycollection中删除“New Jersey”：curl http：//localhost:8983/solr/mycollection/update？commit=true-h“content-type：text/xml”--data-binary'(id:2)'

现在select query只返回剩下的2条记录（删除“New Jersey”）

localhost：8983/solr/mycollection/select？q=%3a&wt=json&indent=true

{
    "responseHeader": {
        "status": 0,
        "QTime": 0,
        "params": {
            "q": "*:*",
            "indent": "true",
            "wt": "json",
            "_": "1448272061874"
        }
    },
    "response": {
        "numFound": 2,
        "start": 0,
        "docs": [
            {
                "id": "1",
                "name": [
                    "New York"
                ],
                "_version_": 1518622755181822000
            },
            {
                "id": "3",
                "name": [
                    "California"
                ],
                "_version_": 1518622755187064800
            }
        ]
    }
}

{
    "responseHeader": {
        "status": 0,
        "QTime": 0
    },
    "spellcheck": {
        "suggestions": [
            "New",
            {
                "numFound": 2,
                "startOffset": 0,
                "endOffset": 3,
                "suggestion": [
                    "New Jersey",
                    "New York"
                ]
            }
        ],
        "collations": [
            "collation",
            "(New Jersey)"
        ]
    }
}

会有什么问题？suggester组件（Solr.SpellCheckComponent）是否使用了任何缓存？如果是，如何清除？

如有任何帮助，我们将不胜感激。

大多数拼写检查器和提示器并不直接从索引中工作，而是建立一个平行的结构。有一个在每次提交的基础上构建的设置，如果该设置为false，则可以在请求中传递一个标志来触发重建。对于拼写检查器，此标志为Spellcheck.build或Spellcheck.reload。

因此，检查您的配置，并尝试显式调用rebuild/reload。
