Info

The first line in the example above contains the field type name, text_general, and the name of the implementing class, solr.TextField. The rest of the definition is about field analysis, described in Understanding Analyzers, Tokenizers, and Filters. The implementing class is responsible for making sure the field is handled correctly. In the class names in schema.xml, the string solr is shorthand for org.apache.solr.schema or org.apache.solr.analysis. Therefore, solr.TextField is really org.apache.solr.schema.TextField.. Field Type Properties The field type class determines most of the behavior of a field type, but optional properties can also be defined. For example, the following definition of a date field type defines two properties, sortMissingLast and omitNorms. The properties that can be specified for a given field type fall into three major categories: Properties specific to the field type's class. General Properties Solr supports for any field type. Field Default Properties that can be specified on the field type that will be inherited by fields that use this type instead of the default behavior. General Properties Property Description Values positionIncrementGap autoGeneratePhraseQueries For multivalued fields, specifies a distance between multiple values, which prevents spurious phrase matches For text fields. If true, Solr automatically generates phrase queries for adjacent terms. If false, terms must be enclosed in double-quotes to be treated as phrases. integer true or false docValuesFormat Defines a custom DocValuesFormat to use for fields of this type. This requires that a schema-aware codec, such as the SchemaCodecFactory has been configured in solrconfig.xml. postingsFormat Defines a custom PostingsFormat to use for fields of this type. This requires that a schema-aware codec, such as the SchemaCodecFactory has been configured in solrconfig.xml. n/a n/a Apache Solr Reference Guide 4.6 30
Lucene index back-compatibility is only supported for the default codec. If you choose to customize the postingsFormat or docValuesFormat in your schema.xml, upgrading to a future version of Solr may require you to either switch back to the default codec and optimize your index to rewrite it into the default codec before upgrading, or re-build your entire index from scratch after upgrading. Field Default Properties Property Description Values indexed If true, the value of the field can be used in queries to retrieve matching documents true or false stored If true, the actual value of the field can be retrieved by queries true or false docValues If true, the value of the field will be put in a column-oriented DocValues structure true or false sortMissingFirst sortMissingLast Control the placement of documents when a sort field is not present. As of Solr 3.5, these work for all numeric fields, including Trie and date fields. true or false multiValued If true, indicates that a single document might contain multiple values for this field type true or false omitNorms omitTermFreqAndPositions If true, omits the norms associated with this field (this disables length normalization and index-time boosting for the field, and saves some memory). Defaults to true for all primitive (non-analyzed) field types, such as int, float, data, bool, and string. Only full-text fields or fields that need an index-time boost need norms. If true, omits term frequency, positions, and payloads from postings for this field. This can be a performance boost for fields that don't require that information. It also reduces the storage space required for the index. Queries that rely on position that are issued on a field with this option will silently fail to find documents. This property defaults to true for all fields that are not text fields. true or false true or false omitPositions Similar to omitTermFreqAndPositions but preserves term frequency information true or false termVectors termPositions termOffsets These options instruct Solr to maintain full term vectors for each document, optionally including the position and offset information for each term occurrence in those vectors. These can be used to accelerate highlighting and other ancillary functionality, but impose a substantial cost in terms of index size. They are not necessary for typical uses of Solr true or false Field Types Included with Solr The following table lists the field types that are available in Solr. The org.apache.solr.schema package includes all the classes listed in this table. Class BCDIntField BCDLongField BCDStrField BinaryField BoolField ByteField CollationField CurrencyField Description Binary-coded decimal (BCD) integer. BCD is a relatively inefficient encoding that offers the benefits of quick decimal calculations and quick conversion to a string. Binary-coded decimal long integer. Binary-coded decimal string. Binary data. Contains either true or false. Values of "1", "t", or "T" in the first character are interpreted as true. Any other values in the first character are interpreted as false. Contains an array of bytes. deprecated, use TrieIntField instead Supports Unicode collation for sorting and range queries. ICUCollationField is a better choice if you can use ICU4J. See the section Unicode Collation. Supports currencies and exchange rates. See the section Working with Currencies and Exchange Rates. DateField Represents a point in time with millisecond precision. See the section Working with Dates. Apache Solr Reference Guide 4.6 31
