As in the feature request was suggested, the stringlength will 
significantly help LIKE operations, if a preselection is made based on 
this value. (Hence a like operation with % would always be equal or 
longer than the specified constant length + the single character 
modification count, if not present: equal)

How can I enable the length storage?
