这是solr的chema 文件，这个文件应该被重命名为"schema.xml",而且他应该放在solrhome/core/conf文件下面。
获取你也能在solr webapp 的classload下面找到他.
性能说明:可以如下来提高性能。
-
设置 stored=“false” 对那些只需要搜索，无需返回的字段.
-
设置 indexed=“false” 对于那些只用于返回无需进行搜索的字段.
-
删除所有不需要 copyfiled字段的声明
-
为了最好的索引大小与索引性能，设置所有一般的文本字段index=false,使用copyfile将他们copy到一个字段上，然后使用它进行搜索。
-
运行jvm服务器模式，并使用较高的日志级别，避免记录每一个请求。
–><!--字段名称应该包含字母数字或下划线字符，不以一个数字开始。这是目前没有严格执行，但其他字段名称将不会有来自所有组件的第一类支持和背部的兼容性没有保证。领导和的名字下划线（如_version_）保留。--> <!--在这data_driven_schema_configs configset，下面三个字段是必须的：
id、version，和_text_。所有其他字段都是可以删除修改的，并根据需要手动添加

请注意，许多动态字段也被定义-您可以使用它们来指定一个
字段的类型通过字段命名约定-见下文。
警告：本_text_catch所字段将会显著地提高索引的大小。

BoolField ： boolean 域，对应 true/false
TrieIntField, TrieFloatField, TrieLongField, TrieDoubleField 这几个都是默认的数字域， precisionStep 属性一般用于数字范围查询， precisionStep 值越小，则索引时该域的域值分出的 token 个数越多，会增大硬盘上索引的体积，但它会加快数字范围检索的响应速度， positionIncrementGap 属性表示如果当前域是多值域时，多个值之间的间距，单值域，设置此项无意义。
TrieDateField ：显然这是一个日期域类型，不过遗憾的是它支持 1995-12-31T23:59:59Z 这种格式的日期，比较坑爹，为此我自定义了一个 TrieCNDateField 域类型，用于支持国人比较喜欢的 yyyy-MM-dd HH:mm:ss 格式的日期。源码请参见我的上一篇博客。
BinaryField ：经过 base64 编码的字符串域类型，即你需要把 binary 数据进行base64 编码才能被 solr 进行索引。
RandomSortField ：随机排序域类型，当你需要实现伪随机排序时，请使用此域类型。
TextField ：是用的最多的一种域类型，它需要进行分词，所以它一般需要配置分词器。至于具体它如何配置 IK 分词器，这里就不展开了–>
