Info

Note: If the source table has a field name identical to one of the default fields from the $TA table, you will receive an error message after the CREATE FULTTEXT INDEX statement informing you to rename the field of the source table. After you rename the corresponding field, you can execute the CREATE FULLTEXT INDEX statement again. 11.1.4 Dropping Full Text Indexes If you want to delete a full text index that you manually created, for example, because it is referenced only rarely or preprocessing is too time-consuming, you can drop the full text index. For TEXT or SHORTTEXT full text indexes, you cannot drop the full text index; instead, you must delete the related column in the table. You also need to drop full text indexes when adding or removing index parameters. As parameters cannot be added to or removed from an existing full text index, if you want to change parameters, you must first drop the full text index and then create a new index with the new parameters. To drop a full text index, you use the DROP FULLTEXT INDEX statement: DROP FULLTEXT INDEX Related Links Note: Before you can drop a full text index, you must remove the relationship between the source table and any existing $TA tables (for text analysis). To do so, use the following statement: ALTER TABLE SCHEMA DROP The name constraint must be the same as originally used when adding the constraint. For more information, see Text Analysis. Altering Full Text Index Parameters [page 246] You can alter a full text index after it is created. Altering an index includes changing the values of the parameters and altering the parameters by replacing the index. Text Analysis [page 242] 11.1.5 Altering Full Text Index Parameters You can alter a full text index after it is created. Altering an index includes changing the values of the parameters and altering the parameters by replacing the index. ● To alter the parameters of a full text index, use the ALTER FULLTEXT INDEX statement. You can only use this statement to alter the following parameters: ○ Fuzzy search index ○ Phrase index ratio Example syntax: ALTER FULLTEXT INDEX PHRASE INDEX RATIO FUZZY SEARCH INDEX ● To alter any other parameter, you must replace the existing full text index as follows: 246 P U B L I C © 2012 SAP AG.

a) Delete the existing full text index by using the DROP FULLTEXT INDEX statement. b) Create a new index using the new parameter values. Related Links Creating Full Text Indexes [page 235] When you create a TEXT or SHORTTEXT column in a table, SAP HANA automatically creates a corresponding full text index. However, for columns of other data types, you must manually create and define any necessary full text indexes. Synchronization [page 240] Full text indexes in a SAP HANA database must be created and updated in synchronization with the corresponding columns. This synchronization can be either synchronous or asynchronous. Queues [page 240] The queue is a mechanism used to enable a full text index to operate asynchronously. This means that when you insert new entries into the column, the text is not made available in the column until it is preprocessed. Full Text Index Parameters [page 247] The content and behavior of a full text index is configured by the use of both default and user-specified parameters. To view the configuration of a full text index, you use the SYS.FULLTEXT_INDEXES view. 11.1.6 Full Text Index Parameters The content and behavior of a full text index is configured by the use of both default and user-specified parameters. To view the configuration of a full text index, you use the SYS.FULLTEXT_INDEXES view. In SAP HANA, full text indexes are configured using the following parameters: Parameter Data Type SCHEMA_NAM E NVARCH AR(256) TABLE_NAME NVARCH AR(256) TABLE_OID BIGINT INDEX_NAME NVARCH AR(256) INDEX_OID BIGINT LANGUAGE_C OLUMN SAP HANA Developer Guide Enabling Search NVARCH AR(256) Default (TEXT) Default (SHORTTEXT) None None None Default (Manually Created) Description Specifies the schema name Specifies the table name Specifies the object ID of the table Specifies the name of the full text index Specifies the object ID of the full text index Specifies the language used for analyzing the document. If no language is specified, automatic language detection is performed. The detected language is stored with the TEXT_AE attribute.
