Solr field type reference for DSE Search
Definitions for Apache Solr field type for DSE Search index schema.
CQL data is parsed into DataStax Enterprise Search indexes using a corresponding Solr field type. The index schema for each table must contain the Solr field type definition along with optional advanced processing instructions.
Trie field types
- 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"/>
- 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"/>
- 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.TrieIntField" name="TrieIntField"/>
- TrieLongField
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.TrieLongField', @name='TrieLongField'];
Results in the following schema XML:
<fieldType class="org.apache.solr.schema.TrieLongField" name="TrieLongField"/>
String field types
- 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"/>
- 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"/>
- 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"/>
- 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"/>
- 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"/>
- TextField
-
ALTER SEARCH INDEX SCHEMA ON table_name ADD types.fieldType[@class='org.apache.solr.schema.TextField', @name='TextField'];
To perform searches containing wildcard characters like % in TextField data, do not use the Lucene StandardAnalyzer class. Instead, define the tokenizer and filters for use in a multiterm search.
- 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"/>
