我有一个名为偏差属性的"文档"(activerecords).该属性的值为"Bin X""Bin $""Bin q""Bin%"等.

我正在尝试使用tire/elasticsearch来搜索属性.我正在使用空白分析器来索引偏差属性.这是我创建索引的代码:

settings :analysis => {
    :filter  => {
      :ngram_filter => {
        :type => "nGram",
        :min_gram => 2,
        :max_gram => 255
      },
      :deviation_filter => {
        :type => "word_delimiter",
        :type_table => ['$ => ALPHA']
      }
    },
    :analyzer => {
      :ngram_analyzer => {
        :type  => "custom",
        :tokenizer  => "standard",
        :filter  => ["lowercase", "ngram_filter"]
      },
      :deviation_analyzer => {
        :type => "custom",
        :tokenizer => "whitespace",
        :filter => ["lowercase"]
      }
    }
  } do
    mapping do
      indexes :id, :type => 'integer'
      [:equipment, :step, …

我在我的分片集合'col'上注意到db.col.count()没有返回实际的文档数(通过使用聚合框架找到).

根据MongoDB文档:

On a sharded cluster, db.collection.count() can result in an inaccurate count if orphaned documents exist or if a chunk migration is in progress.

我正在尝试按照清理孤儿的指示:

db.runCommand( {
   cleanupOrphaned: "my_database.col",
} )

但是,该命令已运行很长时间.查看任何分片上的mongoDB日志,我看到:

2014-11-07T15:33:49.737-0500 [conn862] rangeDeleter waiting for open cursors in: my_database.col, min: { _id: MinKey }, max: { _id: -8172160724588201855 }, cursors: [ 91955293283 ]

这些等待开放游标消息的原因是什么？我该如何解决？
