INDEXING_TYPE_EXACT_TERMS

public static final int INDEXING_TYPE_EXACT_TERMS

Content in this property should only be returned for queries matching the exact tokens appearing in this property.

For example, a property with "fool" should NOT match a query for "foo".

Constant Value: 1 (0x00000001)

INDEXING_TYPE_NONE

public static final int INDEXING_TYPE_NONE

Content in this property will not be tokenized or indexed.

Constant Value: 0 (0x00000000)

INDEXING_TYPE_PREFIXES

public static final int INDEXING_TYPE_PREFIXES

Content in this property should be returned for queries that are either exact matches or query matches of the tokens appearing in this property.

For example, a property with "fool" should match a query for "foo".

Constant Value: 2 (0x00000002)

JOINABLE_VALUE_TYPE_NONE

public static final int JOINABLE_VALUE_TYPE_NONE

Content in this property is not joinable.

Constant Value: 0 (0x00000000)

JOINABLE_VALUE_TYPE_QUALIFIED_ID

public static final int JOINABLE_VALUE_TYPE_QUALIFIED_ID

Content in this string property will be used as a qualified id to join documents.

• Qualified id: a unique identifier for a document, and this joinable value type is similar to primary and foreign key in relational database. See DocumentIdUtil for more details.
• Currently we only support single string joining, so it should only be used with PropertyConfig.CARDINALITY_OPTIONAL and AppSearchSchema.PropertyConfig.CARDINALITY_REQUIRED.

Constant Value: 1 (0x00000001)

TOKENIZER_TYPE_NONE

public static final int TOKENIZER_TYPE_NONE

This value indicates that no tokens should be extracted from this property.

It is only valid for tokenizer_type to be 'NONE' if getIndexingType() is INDEXING_TYPE_NONE.

Constant Value: 0 (0x00000000)

TOKENIZER_TYPE_PLAIN

public static final int TOKENIZER_TYPE_PLAIN

Tokenization for plain text. This value indicates that tokens should be extracted from this property based on word breaks. Segments of whitespace and punctuation are not considered tokens.

For example, a property with "foo bar. baz." will produce tokens for "foo", "bar" and "baz". The segments " " and "." will not be considered tokens.

It is only valid for tokenizer_type to be 'PLAIN' if getIndexingType() is INDEXING_TYPE_EXACT_TERMS or INDEXING_TYPE_PREFIXES.

Constant Value: 1 (0x00000001)

TOKENIZER_TYPE_RFC822

public static final int TOKENIZER_TYPE_RFC822

Tokenization for emails. This value indicates that tokens should be extracted from this property based on email structure.

For example, a property with "alex.sav@google.com" will produce tokens for "alex", "sav", "alex.sav", "google", "com", and "alexsav@google.com"

It is only valid for tokenizer_type to be 'RFC822' if getIndexingType() is INDEXING_TYPE_EXACT_TERMS or INDEXING_TYPE_PREFIXES.

Constant Value: 3 (0x00000003)

TOKENIZER_TYPE_VERBATIM

public static final int TOKENIZER_TYPE_VERBATIM

This value indicates that no normalization or segmentation should be applied to string values that are tokenized using this type. Therefore, the output token is equivalent to the raw string value.

For example, a property with "Hello, world!" will produce the token "Hello, world!", preserving punctuation and capitalization, and not creating separate tokens between the space.

It is only valid for tokenizer_type to be 'VERBATIM' if getIndexingType() is INDEXING_TYPE_EXACT_TERMS or INDEXING_TYPE_PREFIXES.

Constant Value: 2 (0x00000002)

getIndexingType

public int getIndexingType ()

Returns how the property is indexed.

getJoinableValueType

public int getJoinableValueType ()

Returns how this property is going to be used to join documents from other schema types.

getTokenizerType

public int getTokenizerType ()

Returns how this property is tokenized (split into words).
