Solr Schema

Dynamic Field Conventions¶ ↑

The solr schema as found in schema.xml uses a convention with dynamic field names to expose the Solr properties of the field. The following abbreviations are concatenated into the suffix:

• Solr field type abbreviations

  • t for text (language independent)

  • te for English text

  • s for string

  • i for integer

  • dt for date

  • l for long

  • db for double

  • f for float

  • b for boolean

  • ll for location (think lat-lon)

  • trie types are for faster range queries. The t follows the solr field type abbreviation

    • it for trie integer

    • dtt for trie date

    • lt for trie long

    • dbt for trie double

    • ft for trie float

• Solr field properties abbreviations

  • s if stored

  • i if indexed

  • m if multiValued

  • v if termVectors (with termPositions and termOffsets also set to true)

Examples:

<!-- text (_t...) -->
<dynamicField name="*_ti" type="text" stored="false" indexed="true" multiValued="false"/>
<dynamicField name="*_tim" type="text" stored="false" indexed="true" multiValued="true"/>
