- This example schema is the recommended starting point for users.
- It should be kept correct and concise, usable out-of-the-box.
+ This schema will be used by the Apache Stanbol SolrYard implementation to
+ index entities.
+ The implementation of the SolrYard does made several assumptions on
+ configurations defined in this Schema. So changes to this schema that do
+ affect such assumptions will most likelly cause unpredictable errors!
+
+ However there are also a lot of places where users can optimize this schema
+ to specific requirements. See the comments within this schema for more
+ details!
- For more information, on how to customize this file, please see
- http://wiki.apache.org/solr/SchemaXml
+ For more information, on how to customize the Solr schema.xml in general,
+ please see http://wiki.apache.org/solr/SchemaXml.
- PERFORMANCE NOTE: this schema includes many optional features and should not
- be used for benchmarking. To improve performance one could
- - set stored="false" for all fields possible (esp large fields) when you
- only need to search on the field but don't need to return the original
- value.
- - set indexed="false" if you don't need to search on the field, but only
- return the field as a result of searching on other indexed fields.
- - remove all unneeded copyField statements
- - for best index size and searching performance, set "index" to false
- for all general text fields, use copyField to copy them to the
- catchall "text" field, and use that for searching.
- - For maximum indexing performance, use the StreamingUpdateSolrServer
- java client.
- - Remember to run the JVM in server mode, and use a higher logging level
- that avoids logging every request

+ The SolrYard heavily uses dynamic fields to index fields based on there

+ Notes:
+ - By default all dynamicField specifications use multiValued="true"
+ because this schema.xml does not make any assumptions on the data
stored.
+ Even a boolean field may define both "true" and "false" as values.
+ - The SolrYard currently uses only prefixes to represent data types
+ and languages. However postfixes are reserved for future extensions.
+ That means that postfixes MUST NOT be used for dynamicField
definitions

+ <!--
+ DynamicFields representing natural language texts.
+
+ The type of such fields may be changed to one of the alternatives
+ descibed in the types section of this configuration.
+
+ The SolrYard prefixes natural language texts with "@"
+ followed by the defined language.
+ Currently no processing of the language is done. So
+ defineing the language "1xx5zr7" for Text will create
+ a field with the prefix "@1xx5zr7".
+
+ To define a special field type for a language one has
+ to use "@" plus the key for the language as prefix.
+ See the specification for English language texts as example.
+
+ Also prefixes for country specific languages can be
+ realized by defining dynamic fields like follows:
+ use @en* to match en-GB and en-US
+ use @en/* to match only en but not en-GB or en-US
+ use @en-GB/* and @en* to have a special field type for
+ en-GB and one for other english text

+ <!--
+ Dynamic field for english languages.

+ -->
+ <dynamicField name="@en*" type="text_en_Tight" indexed="true"

+ <!--
+ The "@*" catches all the other languages including "@/"
+ (default language) used for texts without a defined language
+ -->
<dynamicField name="@*" type="textgen" indexed="true" stored="true"
multiValued="true"/>
+ <!--
+ To add special configurations for specific fields one
+ has to include the fieldName within the prefix of the
+ dynamicField specification.
+ The SolrYard uses namespace prefixes to generate
+ field names. When defined prefixes defined in the
+ NamespaceEnum of the Entityhub are used.
+ Currently there is no way to define used prefixes for
+ other namespaces.
+
+ This example shows how to activate lower case search
+ for the dcmi-terms format property
+ <dynamicField name="str/dc:format*" type="lowercase" indexed="true"
stored="true" multiValued="true"/>
+
+ This example shows how to activate fast ranged queries

+ <dynamicField name="dou/geo:lon*" type="tdouble" indexed="true"
stored="true" multiValued="true"/>
+ <dynamicField name="int/geo:alt*" type="tint" indexed="true" stored="true"
multiValued="true"/>
+
+ This example defines to use the type "text_en" for
+ english language rdfs:comment values.
+
+ <dynamicField name="@en/rdfs:comment*" type="text_en" indexed="true"
stored="true" multiValued="true"/>
+
+ Note that this would not match "en-GB" nor "en-US".
