        索引存储方案，共有以下存储方案
           1、solr.StandardDirectoryFactory,这是一个基于文件系统存储目录的工厂，它会试图选择最好的实现基于你当前的操作系统和Java虚拟机版本。
           2、solr.SimpleFSDirectoryFactory,适用于小型应用程序，不支持大数据和多线程。
           3、solr.NIOFSDirectoryFactory,适用于多线程环境，但是不适用在windows平台（很慢），是因为JVM还存在bug。
           4、solr.MMapDirectoryFactory,这个是solr3.1到4.0版本在linux64位系统下默认的实现。它是通过使用虚拟内存和内核特性调用
             mmap去访问存储在磁盘中的索引文件。它允许lucene或solr直接访问I/O缓存。如果不需要近实时搜索功能，使用此工厂是个不错的方案。
           5、solr.NRTCachingDirectoryFactory,此工厂设计目的是存储部分索引在内存中，从而加快了近实时搜索的速度。
           6、solr.RAMDirectoryFactory,这是一个内存存储方案，不能持久化存储，在系统重启或服务器crash时数据会丢失。且不支持索引复制

          编解码工厂允许使用自定义的编解码器。例如：如果想启动per-field DocValues格式, 可以在solrconfig.xml里面设置SchemaCodecFactory：
                    docValuesFormat="Lucene42": 这是默认设置，所有数据会被加载到堆内存中。
          docValuesFormat="Disk": 这是另外一个实现，将部分数据存储在磁盘上。

        实验,所以如果你选择定制索引格式,它的好想法通过IndexWriter.addIndexes转换回官方格式如(IndexReader)
        升级到新版本之前,以避免不必要的改变符号。
        当指定ManagedIndexSchemaFactory作为Solr为加载的模式。他在“managedSchemaResourceName”资源命名,而不是schema.xml。
        注意,资源不能叫schema.xml管理模式。如果管理模式不存在,Solr将创建它在阅读模式。xml,然后重命名”模式。xml的“schema.xml.bak”。
        不要手动编辑管理模式——外部修改将被忽略和覆盖的模式修改REST API调用。
        当指定ManagedIndexSchemaFactory可变= true,模式REST API调用将被允许修改,否则,错误响应为这些请求返回。

  <!-- Document Analysis Handler

       http://wiki.apache.org/solr/AnalysisRequestHandler

       An analysis handler that provides a breakdown of the analysis
       process of provided documents. This handler expects a (single)
       content stream with the following format:

       <docs>
         <doc>
           <field name="id">1</field>
           <field name="name">The Name</field>

         </doc>
         <doc>...</doc>
         <doc>...</doc>
         ...
       </docs>

    Note: Each document must contain a field which serves as the
    unique key. This key is used in the returned response to associate
    an analysis breakdown to the analyzed document.

    Like the FieldAnalysisRequestHandler, this handler also supports
    query analysis by sending either an "analysis.query" or "q"
    request parameter that holds the query text to be analyzed. It
    also supports the "analysis.showmatch" parameter which when set to
    true, all field tokens that match the query tokens will be marked
    as a "match".

  <!-- Search Components

       Search components are registered to SolrCore and used by

       <searchComponent name="facet"     class="solr.FacetComponent" />
       <searchComponent name="mlt"       class="solr.MoreLikeThisComponent" />

       <searchComponent name="stats"     class="solr.StatsComponent" />
       <searchComponent name="debug"     class="solr.DebugComponent" />

       Default configuration in a requestHandler would look like:

       <arr name="components">
         <str>query</str>
         <str>facet</str>
         <str>mlt</str>
         <str>highlight</str>
         <str>stats</str>
         <str>debug</str>
       </arr>

       If you register a searchComponent to one of the standard names,
       that will be used instead of the default.

       To insert components before or after the 'standard' components, use:

       <arr name="first-components">
         <str>myFirstComponentName</str>
       </arr>

       <arr name="last-components">
         <str>myLastComponentName</str>

       NOTE: The component registered with the name "debug" will
       always be executed after the "last-components"
