Defining index field types

Default field type definitions

A field type definition is required for parsing CQL columns into the corresponding Solr field type. Add processing instructions to the analyzer section of the fieldType definition.

`TrieField` types

Used with a type attribute and value: integer, long, float, double, date.

TrieDoubleField

<fieldType class="org.apache.solr.schema.TrieDoubleField" name="TrieDoubleField"/>

TrieDateField

Date field for Lucene TrieRange processing, supports indexing negative date. For example: -28011-12-02T00:00:00.002Z. To insert negative dates for the CQL timestamp, insert an epoch time in milliseconds. The TimestampType does not accept a textual representation of negative dates.

<fieldType class="org.apache.solr.schema.TrieDateField" name="TrieDateField"/>

TrieFloatField

<fieldType class="org.apache.solr.schema.TrieFloatField" name="TrieFloatField"/>

StringField types

VarIntStrField

Define with the DataStax class to convert a CQL varint.

<fieldType class="com.datastax.bdp.search.solr.core.types.VarIntStrField" name="VarIntStrField"/>

AsciiStrField

Converts a CQL ascii into a standard Solr StrField.

 <fieldType class="com.datastax.bdp.search.solr.core.types.AsciiStrField"
       name="AsciiStrField"/>

SimpleDateField

Define with the DataStax class to convert a CQL date field into a compatible Solr date field.

<fieldType class="com.datastax.bdp.search.solr.core.types.SimpleDateField" name="SimpleDateField"/>

BoolField

Due to SOLR-7264, setting docValues to true on a boolean field in the Solr schema does not work. A workaround for boolean docValues is to use 0 and 1 with a TrieIntField.

<fieldType class="org.apache.solr.schema.BoolField" name="BoolField"/>

BinaryField

<fieldType class="org.apache.solr.schema.BinaryField" name="BinaryField"/>

UUIDField

A value of this type is a Type 1 UUID that includes the time of its generation. Values are sorted by conflict-free timestamps. For example, use the TimeUUID type to identify a column, such as a blog entry, by its timestamp and allow multiple clients to write to the same partition key simultaneously. To find data mapped from a TimeUUID to a UUIDField, search for the entire UUID value, not just its time component.

<fieldType class="org.apache.solr.schema.UUIDField" name="UUIDField"/>

Default index field definitions for CQL column types

Decimal and varint are indexed as strings. Apache Lucene™ does not support the precision required by these numeric types. Range and sorting queries do not work as expected if a table uses these types.
