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.

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 StreamingUpdateSolrServer
43 java client.
44 - Remember to run the JVM in server mode, and use a higher logging level
45 that avoids logging every request

67 <!-- Valid attributes for fields:
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
99 when adding a document.

1041 <!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer)
1042
1043 Kuromoji has a search mode (default) that does segmentation useful for search. A heuristic
1044 is used to segment compounds into its parts and the compound itself is kept as synonym.
1045
1046 Valid values for attribute mode are:
1047 normal: regular segmentation
1048 search: segmentation useful for search with synonyms compounds (default)
1049 extended: same as search mode, but unigrams unknown words (experimental)
1050
1051 For some applications it might be good to use search mode for indexing and normal mode for
1052 queries to reduce recall and prevent parts of compounds from being matched and highlighted.
1053 Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.
1054
1055 Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
1056 model with your own entries for segmentation, part-of-speech tags and readings without a need
1057 to specify weights. Notice that user dictionaries have not been subject to extensive testing.
1058
1059 User dictionary attributes are:
1060 userDictionary: user dictionary filename
1061 userDictionaryEncoding: user dictionary encoding (default is UTF-8)
1062
1063 See lang/userdict_ja.txt for a sample user dictionary file.
1064
1065 Punctuation characters are discarded by default. Use discardPunctuation="false" to keep them.
1066
1067 See http://wiki.apache.org/solr/JapaneseLanguageSupport for more on Japanese language support.
