Solr7中managed-schema配置詳細說明

schema.xml是什麼?
schema.xml 是用來定義索引數據中的域的,包括域名稱,域類型,域是否索引,是否分詞,是否存儲,是否標準化即 Norms ,是否存儲項向量等等。

schema.xml屬性介紹(一)
schema.xml 配置文件的根元素就是 schema, 有個 name 屬性, name 屬性值可以隨便配,根元素沒什麼好說的, schema 元素下主要有兩個標籤元素即 field 和fieldType,field 表示域,用來定義域, fieldType 用來定義域類型。

schema.xml屬性介紹(二)
field 元素有很多屬性可以配置:
name: 表示域的名稱,是強制必須有的屬性
type: 域類型的名稱,與 fieldType 元素的 name 屬性值對應,也是強制必須有的屬性,不可省略
indexed: true 即表示需要對該域進行索引,一般如果你需要在該域上進行查詢或排序時,則需要配置爲 true, 默認值爲 false
stored: 表示是否需要把域值存儲到硬盤上,方便你後續查詢時能再次提取出來原樣顯示給用戶

schema.xml屬性介紹(三)
docValues: 表示此域是否需要添加一個 docValues 域,這對 facet 查詢, group 分組,排序, function 查詢有好處,儘管這個屬性不是必須的,但他能加快索引數據加載,對 NRT 近實時搜索比較友好,且更節省內存,但它也有一些限制,比如當前docValues 域只支持 strField,UUIDField,Trie*Field 等域,且要求域的域值是單值不能是多值域
multiValued: 表示這個域是否可以存儲多個值,若設置爲 true, 即表示這是一個多值域

schema.xml屬性介紹(四)
omitNorms: 此屬性若設置爲 true ,即表示將忽略域值的長度標準化,忽略在索引過程中對當前域的權重設置,且會節省內存。只有全文本域或者你需要在索引創建過程中設置域的權重時才需要把這個值設爲 false, 對於基本數據類型且不分詞的域如intFeild,longField,StrField 等默認此屬性值就是 true, 否則默認就是 false.
termVectors: 設置爲 true 即表示需要爲該 field 存儲項向量信息,當你需要MoreLikeThis 功能時,則需要將此屬性值設爲 true ,這樣會帶來一些性能提升。
termPositions: 是否存儲 Term 的起始位置信息,這會增大索引的體積,但高亮功能需要依賴此項設置,否則無法高亮

schema.xml屬性介紹(六)
termOffsets: 表示是否存儲索引的位置偏移量,高亮功能需要此項配置,當你使用SpanQuery 時,此項配置會影響匹配的結果集
field 裏還有兩個比較難理解的域,是 Solr 擴展的,在 Lucene 中沒有的概念,即dynamicField 動態域和 copyField 複製域:
動態域的屬性配置跟普通的 field 差不多就不多說了,唯一有點區別就是 name 的屬性值,可以用通配符,這樣就可以模糊匹配多個域啦,這樣設計的目的就是不用頻繁的去修改我們的 schema.xml 中的 field 配置去增加 field 域啦,比如之前有個 link_s域,某一天你想再增加一個 url_s 域,那你就需要去修改 schema.xml 配置文件,由於schema.xml 修改過後需要重啓 tomcat 才能生效,重啓即意味着程序的中斷,這往往是不可接受的。所以引入動態域來避免頻繁添加修改域,但前提是你的域需要符合你提前定義的動態域的域名稱命名規則哦。

schema.xml屬性介紹(七)

複製域即表示把某個域的值複製到一個目標域上面,那如果把多個域的值複製到一個目標域上面呢,你可以進行多次複製,體現到 XML 配置上就是類似這樣的配置:


如上配置就表示把 title 和 body 這兩個域的值全部複製到 text 這個新域上面,唯一要注意的是,如果你只是複製單個域,那麼如果你被複制域本身就是多值域,那麼目標域也是多值域,這毋庸置疑,那如果你複製的是多個域,只要其中有一個域是多值域,那麼目標域就一定是多值域,這點一定要謹記。

 This example schema is the recommended starting point for users.
 It should be kept correct and concise, usable out-of-the-box.

 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.

    <!-- field names should consist of alphanumeric or underscore characters only and
      not start with a digit.  This is not currently strictly enforced,
      but other field names will not have first class support from all components
      and back compatibility is not guaranteed.  Names with both leading and
      trailing underscores (e.g. _version_) are reserved.

           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.
