    value prefixed with field name.
  - getNameLength
```
public static int getNameLength(String namedValue)
```
    Returns the length of the field prefix in namedValue. See also createNamedValue(String, String). If namedValue does not contain a name prefix, this method return 0.
    
    Parameters:
    
    namedValue - the named value as created by createNamedValue(String, String).
    
    Returns:
    
    the length of the field prefix including the separator char '['.
  - isFulltextField
```
public static boolean isFulltextField(String fieldName)
```
    Returns true if the given fieldName denotes a fulltext field like FULLTEXT or a field with a FULLTEXT_PREFIX.
