SELECT ... FROM documents WHERE doc_content LIKE '% Driethanolamyn %' ... Supported SQL data types are ● TEXT ● SHORTTEXT ● Full-text index A full-text index is an additional index structure that can be defined for non-text columns to add text search features. Supported column types are, for example, NCLOB and NVARCHAR. It is possible to speed up the fuzzy search by creating additional data structures, which are used for faster calculation of the fuzzy score. These data structures exist in the memory only, so no additional disk space is required. To create the additional structures, use the flag 'fast_fuzzy_search' when creating a TEXT or SHORTTEXT column or when creating a full-text index. To get the best response times possible, you should enable the fast fuzzy search structures for all database columns that have a high load of fuzzy searches and for all database columns that are used in performance- critical queries. Other Types Fuzzy search is available for the SQL type DATE. A fuzzy search on date values checks for date-specific errors such as dates that lie within a given range of days, or dates where the month and day have been interchanged (for example, American versus British date format). It is not possible to create additional data structures for date types to speed up the search. The queries run with optimal performance without any database tuning. Syntax You can call the fuzzy search by using the CONTAINS() function with the FUZZY() option in the WHERE clause of a SELECT statement. Basic example without additional search options SELECT SCORE() AS score, * FROM documents WHERE CONTAINS(doc_content, 'Driethanolamyn', FUZZY(0.8)) ORDER BY score DESC; Example with additional search options Additional search options that change the default behavior of the fuzzy search can be specified as additional string parameters in the FUZZY() function. SELECT SCORE() AS score, * FROM documents WHERE CONTAINS(doc_content, 'Driethanolamyn', FUZZY(0.8, 'option1=value1, 264 P U B L I C © 2012 SAP AG. All rights reserved.

option2=value2')) ORDER BY score DESC; The search options are specified as a comma-separated list of key-value pairs. Available Fuzzy Search Options Note that some data types in the table below are data-type combinations. ● Text: SQL types TEXT and SHORTTEXT and any columns that have an additional full-text index ● String: SQL types VARCHAR and NVARCHAR ● Date: SQL type DATE Table 14: Available Fuzzy Search Options Name of Option Short Name textSearch ts fulltext, Range Defa ult compare fullte emptyScore es 0.0..1.0 not similarCalculatio nMode spellCheckFacto r abbreviationSimi larity bestMatchingTo kenWeight SAP HANA Developer Guide Enabling Search scm search, compare, symmetri csearch xt set comp are Applies to Types Text, String, Date Text, String, Date Description Switches between full-text search with TF/IDF score and duplicate search with fuzzy score.
