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.
25 This example schema is the recommended starting point for users.
26 It should be kept correct and concise, usable out-of-the-box.
28 For more information, on how to customize this file, please see

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

50 version="x.y" is Solr's version number for the schema syntax and semantics. It should
51 not normally be changed by applications.
52 1.0: multiValued attribute did not exist, all fields are multiValued by nature
53 1.1: multiValued attribute introduced, false by default
54 1.2: omitTermFreqAndPositions attribute introduced, true by default except for text fields.
55 1.3: removed optional field compress feature
56 1.4: default auto-phrase (QueryParser feature) to off
57 1.5: omitNorms defaults to true for primitive field types (int, float, boolean, string...)
61 <!-- Valid attributes for fields:
62 name: mandatory - the name for the field
63 type: mandatory - the name of a field type from the
64 <types> fieldType section
65 indexed: true if this field should be indexed (searchable or sortable)
66 stored: true if this field should be retrievable
67 multiValued: true if this field may contain multiple values per document
68 omitNorms: (expert) set to true to omit the norms associated with
69 this field (this disables length normalization and index-time
70 boosting for the field, and saves some memory). Only full-text
71 fields or fields that need an index-time boost need norms.
72 Norms are omitted for primitive (non-analyzed) types by default.
73 termVectors: [false] set to true to store the term vector for a
75 When using MoreLikeThis, fields used for similarity should be
76 stored for best performance.
77 termPositions: Store position information with the term vector.
78 This will increase storage costs.
79 termOffsets: Store offset information with the term vector. This
80 will increase storage costs.

207 to accelerate range queries when the number of values between the range
208 endpoints is large. See the javadoc for NumericRangeQuery for internal
209 implementation details.
211 Smaller precisionStep values (specified in bits) will lead to more tokens
212 indexed per value, slightly larger index size, and faster range queries.
