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
29 http://wiki.apache.org/solr/SchemaXml
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
48 <schema name="example" version="1.2">
49 <!-- attribute "name" is the name of this schema and is only used for display purposes.
50 Applications should change this to reflect the nature of the search collection.
51 version="1.2" is Solr's version number for the schema syntax and semantics. It should
52 not normally be changed by applications.
53 1.0: multiValued attribute did not exist, all fields are multiValued by nature
54 1.1: multiValued attribute introduced, false by default
55 1.2: omitTermFreqAndPositions attribute introduced, true by default except for text fields.
59 <!-- field type definitions. The "name" attribute is
60 just a label to be used by field definitions. The "class"
61 attribute and any other attributes determine the real
62 behavior of the fieldType.
63 Class names starting with "solr" refer to java classes in the
64 org.apache.solr.analysis package.
67 <!-- The StrField type is not analyzed, but indexed/stored verbatim.
68 - StrField and TextField support an optional compressThreshold which
69 limits compression (if enabled in the derived fields) to values which
70 exceed a certain size (in characters).
72 <fieldType name="string" class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
74 <!-- boolean type: "true" or "false" -->
75 <fieldType name="boolean" class="solr.BoolField" sortMissingLast="true" omitNorms="true"/>
76 <!--Binary data type. The data should be sent/retrieved in as Base64 encoded Strings -->
77 <fieldtype name="binary" class="solr.BinaryField"/>
79 <!-- The optional sortMissingLast and sortMissingFirst attributes are
80 currently supported on types that are sorted internally as strings.
81 This includes "string","boolean","sint","slong","sfloat","sdouble","pdate"
82 - If sortMissingLast="true", then a sort on this field will cause documents
83 without the field to come after documents with the field,
84 regardless of the requested sort order (asc or desc).
85 - If sortMissingFirst="true", then a sort on this field will cause documents
86 without the field to come before documents with the field,
87 regardless of the requested sort order.
88 - If sortMissingLast="false" and sortMissingFirst="false" (the default),
89 then default lucene sorting will be used which places docs without the
90 field first in an ascending sort and last in a descending sort.
94 Default numeric field types. For faster range queries, consider the tint/tfloat/tlong/tdouble types.
96 <fieldType name="int" class="solr.TrieIntField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
97 <fieldType name="float" class="solr.TrieFloatField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
98 <fieldType name="long" class="solr.TrieLongField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
99 <fieldType name="double" class="solr.TrieDoubleField" precisionStep="0" omitNorms="true" positionIncrementGap="0"/>
102 Numeric field types that index each value at various levels of precision
103 to accelerate range queries when the number of values between the range
104 endpoints is large. See the javadoc for NumericRangeQuery for internal
105 implementation details.
107 Smaller precisionStep values (specified in bits) will lead to more tokens
108 indexed per value, slightly larger index size, and faster range queries.
109 A precisionStep of 0 disables indexing at different precision levels.
111 <fieldType name="tint" class="solr.TrieIntField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
112 <fieldType name="tfloat" class="solr.TrieFloatField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
113 <fieldType name="tlong" class="solr.TrieLongField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
114 <fieldType name="tdouble" class="solr.TrieDoubleField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>
116 <!-- The format for this date field is of the form 1995-12-31T23:59:59Z, and
117 is a more restricted form of the canonical representation of dateTime
118 http://www.w3.org/TR/xmlschema-2/#dateTime
119 The trailing "Z" designates UTC time and is mandatory.
120 Optional fractional seconds are allowed: 1995-12-31T23:59:59.999Z
121 All other components are mandatory.
123 Expressions can also be used to denote calculations that should be
124 performed relative to "NOW" to determine the value, ie...
127 ... Round to the start of the current hour
129 ... Exactly 1 day prior to now
130 NOW/DAY+6MONTHS+3DAYS
131 ... 6 months and 3 days in the future from the start of
134 Consult the DateField javadocs for more information.
136 Note: For faster range queries, consider the tdate type
138 <fieldType name="date" class="solr.TrieDateField" omitNorms="true" precisionStep="0" positionIncrementGap="0"/>
140 <!-- A Trie based date field for faster date range queries and date faceting. -->
141 <fieldType name="tdate" class="solr.TrieDateField" omitNorms="true" precisionStep="6" positionIncrementGap="0"/>
146 These should only be used for compatibility with existing indexes (created with older Solr versions)
147 or if "sortMissingFirst" or "sortMissingLast" functionality is needed. Use Trie based fields instead.
149 Plain numeric field types that store and index the text
150 value verbatim (and hence don't support range queries, since the
151 lexicographic ordering isn't equal to the numeric ordering)
153 <fieldType name="pint" class="solr.IntField" omitNorms="true"/>
154 <fieldType name="plong" class="solr.LongField" omitNorms="true"/>
155 <fieldType name="pfloat" class="solr.FloatField" omitNorms="true"/>
156 <fieldType name="pdouble" class="solr.DoubleField" omitNorms="true"/>
157 <fieldType name="pdate" class="solr.DateField" sortMissingLast="true" omitNorms="true"/>
162 These should only be used for compatibility with existing indexes (created with older Solr versions)
163 or if "sortMissingFirst" or "sortMissingLast" functionality is needed. Use Trie based fields instead.
165 Numeric field types that manipulate the value into
166 a string value that isn't human-readable in its internal form,
167 but with a lexicographic ordering the same as the numeric ordering,
168 so that range queries work correctly.
170 <fieldType name="sint" class="solr.SortableIntField" sortMissingLast="true" omitNorms="true"/>
171 <fieldType name="slong" class="solr.SortableLongField" sortMissingLast="true" omitNorms="true"/>
172 <fieldType name="sfloat" class="solr.SortableFloatField" sortMissingLast="true" omitNorms="true"/>
173 <fieldType name="sdouble" class="solr.SortableDoubleField" sortMissingLast="true" omitNorms="true"/>
176 <!-- The "RandomSortField" is not used to store or search any
177 data. You can declare fields of this type it in your schema
178 to generate pseudo-random orderings of your docs for sorting
179 purposes. The ordering is generated based on the field name
180 and the version of the index, As long as the index version
181 remains unchanged, and the same field name is reused,
182 the ordering of the docs will be consistent.
183 If you want different psuedo-random orderings of documents,
184 for the same version of the index, use a dynamicField and
187 <fieldType name="random" class="solr.RandomSortField" indexed="true" />
189 <!-- solr.TextField allows the specification of custom text analyzers
190 specified as a tokenizer and a list of token filters. Different
191 analyzers may be specified for indexing and querying.
193 The optional positionIncrementGap puts space between multiple fields of
194 this type on the same document, with the purpose of preventing false phrase
195 matching across fields.
