schema.xml是什么？
schema.xml 是用来定义索引数据中的域的，包括域名称，域类型，域是否索引，是否分词，是否存储，是否标准化即 Norms ，是否存储项向量等等。
schema.xml属性介绍（一）
schema.xml 配置文件的根元素就是 schema, 有个 name 属性， name 属性值可以随便配，根元素没什么好说的， schema 元素下主要有两个标签元素即 field 和fieldType,field 表示域，用来定义域， fieldType 用来定义域类型。
schema.xml属性介绍（二）
field 元素有很多属性可以配置：
name: 表示域的名称，是强制必须有的属性
type: 域类型的名称，与 fieldType 元素的 name 属性值对应，也是强制必须有的属性，不可省略
indexed: true 即表示需要对该域进行索引，一般如果你需要在该域上进行查询或排序时，则需要配置为 true, 默认值为 false
stored: 表示是否需要把域值存储到硬盘上，方便你后续查询时能再次提取出来原样显示给用户
schema.xml属性介绍（三）
docValues: 表示此域是否需要添加一个 docValues 域，这对 facet 查询， group 分组，排序， function 查询有好处，尽管这个属性不是必须的，但他能加快索引数据加载，对 NRT 近实时搜索比较友好，且更节省内存，但它也有一些限制，比如当前docValues 域只支持 strField,UUIDField,Trie*Field 等域，且要求域的域值是单值不能是多值域
multiValued: 表示这个域是否可以存储多个值，若设置为 true, 即表示这是一个多值域
schema.xml属性介绍（四）
omitNorms: 此属性若设置为 true ，即表示将忽略域值的长度标准化，忽略在索引过程中对当前域的权重设置，且会节省内存。只有全文本域或者你需要在索引创建过程中设置域的权重时才需要把这个值设为 false, 对于基本数据类型且不分词的域如intFeild,longField,StrField 等默认此属性值就是 true, 否则默认就是 false.
termVectors: 设置为 true 即表示需要为该 field 存储项向量信息，当你需要MoreLikeThis 功能时，则需要将此属性值设为 true ，这样会带来一些性能提升。
termPositions: 是否存储 Term 的起始位置信息，这会增大索引的体积，但高亮功能需要依赖此项设置，否则无法高亮
schema.xml属性介绍（六）
termOffsets: 表示是否存储索引的位置偏移量，高亮功能需要此项配置，当你使用SpanQuery 时，此项配置会影响匹配的结果集
field 里还有两个比较难理解的域，是 Solr 扩展的，在 Lucene 中没有的概念，即dynamicField 动态域和 copyField 复制域：
动态域的属性配置跟普通的 field 差不多就不多说了，唯一有点区别就是 name 的属性值，可以用通配符，这样就可以模糊匹配多个域啦，这样设计的目的就是不用频繁的去修改我们的 schema.xml 中的 field 配置去增加 field 域啦，比如之前有个 link_s域，某一天你想再增加一个 url_s 域，那你就需要去修改 schema.xml 配置文件，由于schema.xml 修改过后需要重启 tomcat 才能生效，重启即意味着程序的中断，这往往是不可接受的。所以引入动态域来避免频繁添加修改域，但前提是你的域需要符合你提前定义的动态域的域名称命名规则哦。
schema.xml属性介绍（七）
复制域即表示把某个域的值复制到一个目标域上面，那如果把多个域的值复制到一个目标域上面呢，你可以进行多次复制，体现到 XML 配置上就是类似这样的配置：
如上配置就表示把 title 和 body 这两个域的值全部复制到 text 这个新域上面，唯一要注意的是，如果你只是复制单个域，那么如果你被复制域本身就是多值域，那么目标域也是多值域，这毋庸置疑，那如果你复制的是多个域，只要其中有一个域是多值域，那么目标域就一定是多值域，这点一定要谨记。

<!--
This example schema is the recommended starting point for users.
It should be kept correct and concise, usable out-of-the-box.
For more information, on how to customize this file, please see
http://lucene.apache.org/solr/guide/documents-fields-and-schema-design.html
PERFORMANCE NOTE: this schema includes many optional features and should not
be used for benchmarking. To improve performance one could
- set stored="false" for all fields possible (esp large fields) when you
only need to search on the field but don't need to return the original
value.
- set indexed="false" if you don't need to search on the field, but only
return the field as a result of searching on other indexed fields.
- remove all unneeded copyField statements
- for best index size and searching performance, set "index" to false
for all general text fields, use copyField to copy them to the
catchall "text" field, and use that for searching.
-->
<schema name="default-config" version="1.6">
<!-- attribute "name" is the name of this schema and is only used for display purposes.
version="x.y" is Solr's version number for the schema syntax and
semantics. It should not normally be changed by applications.
1.0: multiValued attribute did not exist, all fields are multiValued
by nature
1.1: multiValued attribute introduced, false by default
1.2: omitTermFreqAndPositions attribute introduced, true by default
except for text fields.
1.3: removed optional field compress feature
1.4: autoGeneratePhraseQueries attribute introduced to drive QueryParser
behavior when a single string produces multiple tokens. Defaults
to off for version >= 1.4
1.5: omitNorms defaults to true for primitive field types
(int, float, boolean, string...)
1.6: useDocValuesAsStored defaults to true.

<!-- Valid attributes for fields:
name: mandatory - the name for the field
type: mandatory - the name of a field type from the
fieldTypes section
indexed: true if this field should be indexed (searchable or sortable)
stored: true if this field should be retrievable
docValues: true if this field should have doc values. Doc Values is
recommended (required, if you are using *Point fields) for faceting,
grouping, sorting and function queries. Doc Values will make the index
faster to load, more NRT-friendly and more memory-efficient.
They are currently only supported by StrField, UUIDField, all
*PointFields, 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)
multiValued: true if this field may contain multiple values per document
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.
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.
termPositions: Store position information with the term vector.
This will increase storage costs.
termOffsets: Store offset information with the term vector. This
will increase storage costs.
required: The field is required. It will throw an error if the
value does not exist
default: a value that should be used if no value is specified
when adding a document.

<!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer)
Kuromoji has a search mode (default) that does segmentation useful for search. A heuristic
is used to segment compounds into its parts and the compound itself is kept as synonym.
Valid values for attribute mode are:
normal: regular segmentation
search: segmentation useful for search with synonyms compounds (default)
extended: same as search mode, but unigrams unknown words (experimental)
For some applications it might be good to use search mode for indexing and normal mode for
queries to reduce recall and prevent parts of compounds from being matched and highlighted.
Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.
Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
model with your own entries for segmentation, part-of-speech tags and readings without a need
to specify weights. Notice that user dictionaries have not been subject to extensive testing.
User dictionary attributes are:
userDictionary: user dictionary filename
userDictionaryEncoding: user dictionary encoding (default is UTF-8)
See lang/userdict_ja.txt for a sample user dictionary file.
Punctuation characters are discarded by default. Use discardPunctuation="false" to keep them.
