 This is the Solr schema file. This file should be named "schema.xml" and
 should be in the conf directory under the solr home
 (i.e. ./solr/conf/schema.xml by default) 
 or located where the classloader for the Solr webapp can find it.

 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://wiki.apache.org/solr/SchemaXml

 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.
  - For maximum indexing performance,use the StreamingUpdateSolrServer
    java client.
  - Remember to run the JVM in server mode,and use a higher logging level
    that avoids logging every request

	性能提示:该schema包含许多可选的特性,并且不应该作为基准(配置)。为了提升性能,你可以
	1.设置所有的,尤其是大字段的stored="false",当你只根据该字段进行搜索,而不用(在搜索结果中)返回该字段的原始值。
	2.如果你不需要根据某个字段进行搜索,该字段仅作为对其他字段进行搜索的结果返回,则设置该字段的indexed="false"。
	3.移除所有不需要的copyField字段的声明。
	4.为达到最佳的索引大小以及搜索性能,将所有一般性的text(文本)字段的indexed属性设置为false,并且使用copyField,将这些字段复制到名为text的字段,并用该字段进行搜索。
	5.为达到最佳搜索性能,使用StreamingUpdateSolrServer的java客户端。
	6.记得将jvm运行在server mode下,并使用高一些的日志级别,以免打印出所有的请求日志。

<schema name="example" version="1.5">
  <!-- 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.
	   (译:引入omitTermFreqAndPositions属性,除了文本字段外,默认为true.)
       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...)
	   (译:对基本的字段类型(int,string...),omitNorms(取消算分因子)默认为true)
	   (补:
		  omitNorms - 取消算分因子
			.nrm file
			字段的omitNorms=false的话,会保存这个字段上各个DOC的算分因子,其文件格式如下
			[N,R,M,-1][bytes size=doc num][bytes size=doc num][bytes size=doc num]
			头文件标示,接下来是三个omitNorms=false的字段下各个document的算分因子
			在建索引时可以为DOC设定一个分数,DOC下各个字段也可以设定一个分数
			norm[doc][filed] = sorce(doc)*sorce(filed) | float -> byte 故精确性因为使用不当而不好
			搜索时最终的算分是经过norm[doc][filed]累乘了的
		  storePayloads - payloads 用来存放TERM在DOC出现时的属性,可以是以后用来算分的因子,也可以是
			是其它的属性,在搜索时可以选择用不用这块的数据,以及怎么用。其特点是TERM在DOC里的每次出现
			都能有一个payload属性,这个值是在分词组件时切词时设置的。lucene为这块提供的灵活性还是很高
		  omitTermFreqAndPositions - 有些字段在搜索时不需要TERM在DOC里的FREQ,POS信息,只要通过TERM
			能定位到DOC就满足了,这样的字段omitTermFreqAndPositions最好设置成true. 这样的字段一般不会
			有TERM间模糊查询,当然还有payload属性(因为payload是跟随POS的)。

<fields>
   <!-- Valid attributes for fields:
     name: mandatory - the name for the field
     type: mandatory - the name of a field type from the 
       <types> fieldType 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 are
       useful for faceting,grouping,sorting and function queries. Although 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 Trie*Fields,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.
	   
	  (译:
		docValues:
		multiValued:
			如果文档的某个字段可能包含多个值,设置为true。
		omitNorms:
			如果设置为true,则忽略该字段的标准化因子,这会禁用该字段
			的长度标准化(即字段的长度不再影响打分)和索引时的boosting(权重值),并且节省一些内存。仅完全的文本字段或者需要索引时boost权重值的字段需要
			标准化因子。对于不被(分词器)分析的基本类型,标准化因子默认被忽略。
		termVectors:
			默认false。设置为true,则保存该字段的词元向量。当使用MoreLikeThis查询,字段被用于相似性查询,该属性需要被使用以达到最佳效果。
		termPositions:
			存储termVectors的位置信息,这会增加存储开销。

         remains unchanged,and the same field name is reused,the ordering of the docs will be consistent.  
         If you want different psuedo-random orderings of documents,for the same version of the index,use a dynamicField and
         change the field name in the request.

      <!-- 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.

           See http://wiki.apache.org/solr/JapaneseLanguageSupport for more on Japanese language support.
