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:
