Specifying logical types
You must specify the logical type of a property type to inform your deployment about the type of data it is processing so it can enable and disable operators. By specifying the logical type, you can enter or import data more accurately through validation checking.
A property with the single-line string logical type is used to store text that can be used for faceting, and supports operations such as 'Starts with' and 'Ends with'. A property with the multi-line string logical type can be used to store larger blocks of information, but the values cannot be used for faceting or operations such as 'Start with' and 'Ends with'.
A property with the single-line string logical type can contain a maximum of 8000 characters in Db2 databases, or 4000 characters in SQL Server databases.
- In the tab of your chosen property type, select a logical type from the Logical type list. The default logical type is Single Line String.

entry name tab description entry name tab description
- The first line of the import file is ignored.
For the Single Line String, you can specify the Maximum
Note: To help reduce performance issues, the default length for single-line strings is 250 characters, increasing this limit affects performance and must be tested.
