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

53       1.0: multiValued attribute did not exist, all fields are multiValued
54            by nature
55       1.1: multiValued attribute introduced, false by default
56       1.2: omitTermFreqAndPositions attribute introduced, true by default
57            except for text fields.
58       1.3: removed optional field compress feature
59       1.4: autoGeneratePhraseQueries attribute introduced to drive QueryParser
60            behavior when a single string produces multiple tokens.  Defaults
61            to off for version >= 1.4

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.

1015      <!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer)
1016
1017           Kuromoji has a search mode (default) that does segmentation useful for search.  A heuristic
1018           is used to segment compounds into its parts and the compound itself is kept as synonym.
1019
1020           Valid values for attribute mode are:
1021              normal: regular segmentation
1022              search: segmentation useful for search with synonyms compounds (default)
1023            extended: same as search mode, but unigrams unknown words (experimental)
1024
1025           For some applications it might be good to use search mode for indexing and normal mode for
1026           queries to reduce recall and prevent parts of compounds from being matched and highlighted.
1027           Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query.
1028
1029           Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
1030           model with your own entries for segmentation, part-of-speech tags and readings without a need
1031           to specify weights.  Notice that user dictionaries have not been subject to extensive testing.
1032
1033           User dictionary attributes are:
1034                     userDictionary: user dictionary filename
1035             userDictionaryEncoding: user dictionary encoding (default is UTF-8)
1036
1037           See lang/userdict_ja.txt for a sample user dictionary file.
1038
1039           Punctuation characters are discarded by default.  Use discardPunctuation="false" to keep them.
