The possible combinations resulting from resolving of yellow fields can be huge and extremely increase the index. That's why the allowed number of variants per catalog and per project is restricted by configuration file.
The setting is
performed via configuration file partsol.cfg and applies for all
catalogs.
MaxProjectResolveRangemeans, the stated number of variants must not be exceeded per project by the resolving of value ranges.INDEX:LUCENE MaxProjectResolveRange=25000 (default)
MaxCatalogResolveRangemeans, the stated number of variants must not be exceeded per catalog by the resolving of value ranges.INDEX:LUCENE MaxCatalogResolveRange=50000 (default)
If one of these limits is exceeded, then no variants are indexed for the whole catalog. If a search for value range values shall be successful, a Reverse Search has to be used.
