ELO provides different types of index fields. You should select the appropriate index field type depending on the application and your requirements.

To select this type of index field in the ELO Administration Console, go to Index field templates > Input > Data type.

You can choose from the following types of index fields:

Text: In Text index field types, you can enter any characters.

File reference: Import a file reference from the file reference generator.

Date: In Date index field types, the user can select a date from an integrated calendar.

Please note: The index field type Date is only provided for compatibility reasons. Please use the ISO date index field type instead.

ISO date: In ISO date index field types, the user can select a date from an integrated calendar. The date is saved in ISO format (YYYYMMDD).

List entry: In the List entry index field type, the user must store a hierarchical keyword list in a text file. The user selects keywords from this list when keywording a folder or document.

Please note: The List entry Index field type is available for compatibility reasons. In newer ELO client versions, this index field type is treated the same as the Text index field type.

Number: In Number type index fields, you can only enter numbers and number separators. If you enter any other characters in this field, a warning message will appear.

Numeric fixed width: You can only enter numbers and number separators to a Numeric fixed width index field type. If you enter any other characters in this field, a warning message will appear. If you see this message, correct your entry. You must enter a value greater than zero to the Maximum length field to define the width.

Numeric fixed with 1,2, 4 or 6 decimal places: In the index field type Numeric fixed width, x decimal places, you can only enter numbers and corresponding number separators. You must enter a value greater than zero to the Maximum length field to define the width.

If you enter a number during keywording, it will be automatically be completed according to the following convention:

• Number without decimal point: ELO will automatically add a decimal point and the selected number of decimal places (always zeros).
• Number with decimal point: ELO will add zeros after the last decimal until the required number of decimal places has been reached.

Information: ELO will also add decimals when the maximum number of characters for a field has been reached.

Example 1

The setting Numeric, fixed width, 2 decimal places is selected. If the user enters the value "1" to the index field, ELO will change it to 1.00.

Example 2

The setting Numeric, fixed width, 4 decimal places is selected. If the user enters the value "4.2" to the index field, ELO will change it to 4.2000.

This ensures that entries always have the same number of decimal places.

Thesaurus: The Thesaurus index field type provides word groups in an index field which the user can select from a menu in a dialog box. Right-click the corresponding index field to open the dialog box.

User field: You can right-click index fields of the type User field to open a list of all active users and groups in ELO.

Relation: Relation index field types are used to link an index field with keywording information for another entry.

The following conditions must be met before you can transfer keywording information to a Relation index field type:

• There must be at least one keywording form with the usage Relation.
• The required keywording forms must be entered to the Relation field in the index field template.

Please note: The keywording form with the usage Relation must be created before the corresponding index fields.
