当type声明为string,Elasticsearch 6.0将显示此错误.

"name" => [
  "type" => "string",
  "analyzer" => "ik_max_word"
]

我们title在索引中存储了一个字段,并希望将该字段用于两个目的:

1. 我们正在使用ngram过滤器进行分析,因此我们可以提供自动完成和即时结果
2. 我们希望能够在title字段上使用ASC排序列出结果而不是分数.

索引/过滤器/分析器的定义如下:

array(
    'number_of_shards' => $this->shards,
    'number_of_replicas' => $this->replicas,
    'analysis' => array(
        'filter' => array(
            'nGram_filter' => array(
                'type' => 'nGram',
                'min_gram' => 2,
                'max_gram' => 20,
                'token_chars' => array('letter','digit','punctuation','symbol')
            )
        ),

        'analyzer' => array(
            'index_analyzer' => array(
                'type' => 'custom',
                'tokenizer' =>'whitespace',
                'char_filter' => 'html_strip',
                'filter' => array('lowercase','asciifolding','nGram_filter')
            ),
            'search_analyzer' => array(
                'type' => 'custom',
                'tokenizer' =>'whitespace',
                'char_filter' => 'html_strip',
                'filter' => array('lowercase','asciifolding')
            )
        )
    )
),

当我们对title场地进行排序时,我们遇到的问题是不可预测的结果.在做了一点搜索之后,我们sort在ElasticSearch 的手册页末尾发现了这个...( …

我在弹性搜索上按日期排序时遇到问题。根据elasticsearch提供的文档http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_sorting.html

我使用以下代码按日期排序

{"sort":{"posted_on":{"order":"desc"}}}

以下是结果
