  20. This is the Solr schema file. This file should be named "schema.xml" and
  21. should be in the conf directory under the solr home
  22. (i.e. ./solr/conf/schema.xml by default)
  23. or located where the classloader for the Solr webapp can find it.
  24.  
  25. This example schema is the recommended starting point for users.
  26. It should be kept correct and concise, usable out-of-the-box.
  27.  
  28. For more information, on how to customize this file, please see
  29. http://wiki.apache.org/solr/SchemaXml
  30.  
  31. PERFORMANCE NOTE: this schema includes many optional features and should not
  32. be used for benchmarking.  To improve performance one could
  33.  - set stored="false" for all fields possible (esp large fields) when you
  34.    only need to search on the field but don't need to return the original
  35.    value.
  36.  - set indexed="false" if you don't need to search on the field, but only
  37.    return the field as a result of searching on other indexed fields.
  38.  - remove all unneeded copyField statements
  39.  - for best index size and searching performance, set "index" to false
  40.    for all general text fields, use copyField to copy them to the
  41.    catchall "text" field, and use that for searching.
  42.  - For maximum indexing performance, use the ConcurrentUpdateSolrServer
  43.    java client.
  44.  - Remember to run the JVM in server mode, and use a higher logging level
  45.    that avoids logging every request

  68.     name: mandatory - the name for the field
  69.     type: mandatory - the name of a field type from the
  70.       <types> fieldType section
  71.     indexed: true if this field should be indexed (searchable or sortable)
  72.     stored: true if this field should be retrievable
  73.     docValues: true if this field should have doc values. Doc values are
  74.       useful for faceting, grouping, sorting and function queries. Although not
  75.       required, doc values will make the index faster to load, more
  76.       NRT-friendly and more memory-efficient. They however come with some
  77.       limitations: they are currently only supported by StrField, UUIDField
  78.       and all Trie*Fields, and depending on the field type, they might
  79.       require the field to be single-valued, be required or have a default
  80.       value (check the documentation of the field type you're interested in
  81.       for more information)
  82.     multiValued: true if this field may contain multiple values per document
  83.     omitNorms: (expert) set to true to omit the norms associated with
  84.       this field (this disables length normalization and index-time
  85.       boosting for the field, and saves some memory).  Only full-text
  86.       fields or fields that need an index-time boost need norms.
  87.       Norms are omitted for primitive (non-analyzed) types by default.
  88.     termVectors: [false] set to true to store the term vector for a
  89.       given field.
  90.       When using MoreLikeThis, fields used for similarity should be
  91.       stored for best performance.
  92.     termPositions: Store position information with the term vector.  
  93.       This will increase storage costs.
  94.     termOffsets: Store offset information with the term vector. This
  95.       will increase storage costs.
  96.     required: The field is required.  It will throw an error if the
  97.       value does not exist
  98.     default: a value that should be used if no value is specified

  782.           For some applications it might be good to use search mode for indexing and normal mode for
  783.           queries to reduce recall and prevent parts of compounds from being matched and highlighted.
  784.           Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.
  785.  
  786.           Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
  787.           model with your own entries for segmentation, part-of-speech tags and readings without a need
  788.           to specify weights.  Notice that user dictionaries have not been subject to extensive testing.
  789.  
  790.           User dictionary attributes are:
  791.                     userDictionary: user dictionary filename
  792.             userDictionaryEncoding: user dictionary encoding (default is UTF-8)
  793.  
  794.           Punctuation characters are discarded by default.  Use discardPunctuation="false" to keep them.

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