Initial SOLRJ development and Schema.xml configuration and service initialization.

Schema.xml is located in the solr/collection1/conf/directory and is the configuration file for user-defined field types and fields in SOLR.

SOLR version: 4.6.0

The first step: Schema.xml description

The example Schema.xml structure is consistent with the solr/collection1/conf/schema.xml structure, and the specific configuration is indicated by the annotation.

<?xml version= "1.0" encoding= "UTF-8"?> <schema name= "Example" version= "1.5" > <fields> <!--
         Field Property Description: The filed field is used to define the type of search and related settings used by the Data source field.
         Name: The data source field name, which is used by the search.
         Type: Search for a kind name such as Chinese Ika search name Text_ika, corresponding to name in FieldType. String types that do not need to be participle, string can be, if you need to participle, types in the configuration of a good word type.
         Indexed: Indexed, only fields set to true can be searched for sort fragmentation (earchable, sortable, facetable).
         Stored: whether to store content, if you do not need to store field values, try to set to false to improve efficiency. Multivalued: is a multivalued type, SOLR allows you to configure multiple data source fields to be stored in a search field.
     Multiple values must be true, otherwise it is possible to throw an exception. --> <field name= "id" type= "string" indexed= "true" stored= "true" required= "true"/> <field n Ame= "name" type= "Text_ik" indexed= "true" stored= "true" multivalued= "false"/> <field name= "Phone" type= "string" Indexed= "false" stored= "true"/> <field name= "Email" type= "string" indexed= "false" stored= "true" multivalued= "t Rue "/> <field name=" city_id "type=" "true" indexed= "true" stored=/> <field "Address" tYpe= "Text_ik" index= "true" stored= "true"/> <field name= "All" type= "string" index= "true" stored= "true"/>

In the default Solr/collection1/conf/schema.xml file, there is the following field setting, where title is configured to allow multiple values, so we can use the collection to mark the abstract class.

<field name= "id" type= "string" indexed= "true" stored= "true" required= "true" multivalued= "false"/>
<field name= "title" Type= "Text_general" indexed= "true" stored= "true" multivalued= "true"/>
<field name= "Author" type= "Text_general" indexed= "true" stored= "true"/>
