With V12, index management is based on a new JavaLucene index, which is activated under $CADENAS_SETUP/partsol.cfg is activated in the following key.
[INDEX:LUCENE] JavaLucene=1
Even if a complete index from V11 is available, the full text index [Full-text index] for V12 must be completely regenerated. The LinkDB index must also be recreated as it also uses the new index type. The geoindex [Geo index] is immediately displayed correctly; however, it should also be regenerated as there are new algorithms that extend the search options.
The figures shows the situation after switching to the new index. In this example, only for "ANSI / ASME", "commonpool" and "Assistent" catalog, the new index has been created.
