solr相关配置翻译
　　name: mandatory - the name for the field
　　name : 字段名称，必填
　　type: mandatory - the name of a field type from the fieldTypes
　　type: 字段类型集中fieldTypes的字段类型名称,必填
　　indexed: true if this field should be indexed (searchable or sortable)
　　indexed: 设置为true的话该字段将被索引（可以查询或排序）
　　stored: true if this field should be retrievable
　　stored: 设置为true表示该字段将被存储; false时查询时不返回该内容，但不影响索引
　　docValues: true if this field should have doc values. Doc values are

　　useful for>　　not required, doc values will make the index faster to load, more
　　NRT-friendly and more memory-efficient. They however come with some
　　limitations: they are currently only supported by StrField, UUIDField
　　and all TrieFields, and depending on the field type, they might
　　require the field to be single-valued, be required or have a default
　　value (check the documentation of the field type you're interested in
　　for more information)
　　docValues: 设置为true该字段应该有docValues, docValues有益于faceting,grouping,sorting和函数查询，docValues将使索引加载更快，近实时查询(NRT?)更有好，更加节省内存.但是也有一些限制，当前仅StrField，UUIDField和所有的 Trie(字典树）类型支持)，而且依赖字段类型，可能要求字段为单值的（single-valued），必填或有默认值
　　multiValued: true if this field may contain multiple values per document
　　multiValued：设置为true如果该字段在单个文档中可以有多个值
　　omitNorms: (expert) set to true to omit the norms associated with
　　this field (this disables length normalization and index-time
　　boosting for the field, and saves some memory). Only full-text
　　fields or fields that need an index-time boost need norms.
　　Norms are omitted for primitive (non-analyzed) types by default.
　　omitNorms：(专业级)设置为true将忽略些字段上关联的规则(将禁用对于此字段的长度标准化及索引时间及内存的优化）.只有纯文本或需要索引时间优化的字段需要规则。原始类型(不要分解)默认忽略规则。
　　termVectors: [false] set to true to store the term vector for a
　　given field.When using MoreLikeThis, fields used for similarity should be
　　stored for best performance.
　　termVectors：[默认false]设置为true将保存索引向量
　　termPositions: Store position information with the term vector.
　　This will increase storage costs.
　　termPositions：保存索引向量位置信息
　　termOffsets: Store offset information with the term vector.
　　This will increase storage costs.
　　termOffsets：保存索引向量偏移信息
　　required: The field is required. It will throw an error if the
　　value does not exist
　　required：该字段是必须的，如果没有将报错
　　default: a value that should be used if no value is specified
　　when adding a document.
　　default: 增加文档时，如果该字段未指定值，将使用该默认值
