Documentation
Definition
The full text fuzzy search can, if required, be modeled so that the search query is interpreted in an error-tolerant way. Consequently, it is then possible for matching results to be found whenever the search query - perhaps due to spelling or typing errors - is slightly different from the values in the database. With the help of the accuracy value, it is possible to set how exactly the search query and the values in the database must match.
Use
The value can be set in one-tenth increments form 0.1 to 1.0, whereby 0.1 produces an extremely error-tolerant full text search and 1.0 models an exact full text search. If the full text fuzzy search is activated for the respective search help, the default value 0.8 is automatically used to start with. As a rule, this value produces good correction of spelling errors, without generating too many unwanted hits.
Dependencies
This value takes effect solely for the full text fuzzy search and can therefore only be changed if this function is activated for the respective search help.
Example
A search help uses a database table with customer numbers as well as the name and location of the customer. With the error-tolerant full text search, users can now also find customer numbers if they enter, for example, "Waldorf" instead of the correct name "Walldorf" for the location of the customer.
