Search index field type classes
Definitions for DSE Search index schema field types.
Indexing data from a CQL column using DataStax Enterprise Search, parses the CQL data into a corresponding Solr field. The index schema for each table must contain the Solr field type definition along with optional advanced processing instructions.
Trie field types
- TrieDoubleField
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class=org.apache.solr.schema.TrieDoubleField', @name='TrieDoubleField'];
Results in the following schema XML:
<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.
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.TrieDateField', @name='TrieDateField'];
Results in the following schema XML:
<fieldType class="org.apache.solr.schema.TrieDateField" name="TrieDateField"/>
- TrieFloatField
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.TrieFloatField', @name='TrieFloatField'];
Results in the following schema XML:
<fieldType class="org.apache.solr.schema.TrieFloatField" name="TrieFloatField"/>
- TrieIntField
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.TrieIntField', @name='TrieIntField'];
Results in the following schema XML:
<fieldType class="org.apache.solr.schema.TrieFloatField" name="TrieFloatField"/>
String field types
- VarIntStrField
- Define with the DataStax class to convert a CQL varint.
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='com.datastax.bdp.search.solr.core.types.VarIntStrField', @name='VarIntStrField'];
Results in the following schema XML:
<fieldType class="com.datastax.bdp.search.solr.core.types.VarIntStrField" name="VarIntStrField"/>
- AsciiStrField
- Converts a CQL ascii into a standard Solr
StrField.
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='com.datastax.bdp.search.solr.core.types.AsciiStrField', @name='AsciiStrField'];
Results in the following Schema XML:
<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.
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='com.datastax.bdp.search.solr.core.types.SimpleDateField', @name='SimpleDateField'];
Results in the following Schema XML:
<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.
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.BoolField', @name='BoolField'];
Results in the following Schema XML:
<fieldType class="org.apache.solr.schema.BoolField" name="BoolField"/>
- BinaryField
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.BinaryField', @name='BinaryField'];
Results in the following Schema XML:
<fieldType class="org.apache.solr.schema.BinaryField" name="BinaryField"/>
- UUIDField
- UUIDFIeld is a type 1 UUID data type, which 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.
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.UUIDField', @name='UUIDField'];
Results in the following Schema XML:
<fieldType class="org.apache.solr.schema.UUIDField" name="UUIDField"/>
- TextField
-
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.TextField', @name='TextField'];
