freestyler to the additional hidden TEXT column. In this case, the mode textsearch=compare and all fuzzy search options are allowed: CREATE COLUMN TABLE mytable ( col1 SHORTTEXT(200) ); SELECT score() AS score, * FROM mytable WHERE contains(col1, 'a b', fuzzy(0.8, 'textsearch=compare')); Fuzzy Search on a FULLTEXT INDEX When a full text index is created on a column that is not of type TEXT (e.g. NVARCHAR, NCLOB, ...) a hidden text column is added to the table. A call to contains that references the non-TEXT column is automatically redirected by the freestyler to the additional text column. In this case, the mode textsearch=compare and all fuzzy search options are allowed: CREATE COLUMN TABLE mytable ( col1 NVARCHAR(2000) ); CREATE FULLTEXT INDEX myindex ON mytable(col1); SELECT score() AS score, * FROM mytable WHERE contains(col1, 'a b', fuzzy(0.8, 'textsearch=compare')); Merge Delta for Better Performance When inserting or loading a large number of rows in a table that has a TEXT or SHORTTEXT column or that uses a FULLTEXT INDEX, it is important to merge the delta part of the table to get a good search performance. A delta merge can be started manually with the following SQL statement: MERGE DELTA OF mytable; Alternatively, a delta merge can be triggered automatically by the mergedog process. Fuzzy Multi-Token Search on Text Columns Content Types When using more than one token within a query, the default content type is AND (for example, ... WHERE CONTAINS (mycolumn, 'software firm', FUZZY(0.5)) ... will return entries that contain a token similar to 'software' and a token similar to 'firm'). Alternatively, you can use OR by adding the key word between the tokens (for example, ... WHERE CONTAINS (mycolumn, 'apple OR 'banana', FUZZY(0.5)) ... will return entries that contain a token similar to 'apple' and entries that contain a token similar to 'banana'). 282 P U B L I C © 2012 SAP AG. All rights reserved. SAP HANA Developer Guide Enabling Search
PHRASE is similar to AND but restricts hits to those that contain the tokens as a phrase, that is, in the same order and with nothing between them. A PHRASE is indicated by adding double quotes around the tokens, within the single quotes (for example, ... WHERE CONTAINS (mycolumn, '"day dream"', FUZZY(0.5)) ... will not return an entry containing 'I dream of a day'). The content type AND that is used for a full-text search (default behavior: textSearch=fulltext) is implemented as a logical AND to achieve better performance. For example, a search for 'Miller & Miller AG' with content type AND matches 'Miller AG'. textSearch=compare should be used for duplicate detection and for comparing company names, product names, and so on. Here, search results are better because of the strict AND comparison that is used. In other words, if you search for 'Miller & Miller' with content type AND, only records that contain the term 'Miller' at least twice are returned. A strict AND assigns terms from the user input to terms in the database entry only once (and vice versa). For more information, see Fuzzy Multi-Token Search with Soft AND [page 285]. Parameters Influencing the Score Name of Option Range Default Applies to Types bestMatchingTokenWeigh t considerNonMatchingTok ens Formula for score calculation: 0.0..1.0 not set TEXT max, min, all, input, table max TEXT score = bestMatchingTokenWeight x max(tokenScores) + (1-bestMatchingTokenWeight) x √(Σ(tokenScore²)/ tokenCount) tokenCount is determined according to the parameter considerNonMatchingTokens as follows: ● input: Use search term token count ● table: Use column value token count ● all: Use sum of search and column value token count (where the numerator is multiplied by 2) ● min: Use smaller value of token counts ● max: Use larger value of token counts (default) Recommendations for specific search content types If you are using an "OR" search (searching for "this or that"), you should set considerNonMatchingTokens to table to get a useful score assessment.
