If you made an update V10 to V11 (major release) or on update of service pack (e.g. V11 SP0 to SP9), you should update the geo-index. For all other combinations you have to check the features if it’s important for your customer.
If you use geosearch / topo search also for the psol catalogs (not only native customer catalog), you should update the geo index in PARTadmin for all catalogs. If you only install a new update of a catalog (new cip), the fixes will not be active because CIPs are generated with an old psol release and so your psol installation doesn’t fit together with the installed geo index. The geosearch / toposearch will work but not as good as when having a geo index with all the improvements and the fixed topics.
-> For native geosearch catalogs this is ok, because the geo index will be updated with the installed version at your customer. So you always get the correct index.
-> But if you update or install psol catalogs from time to time you will get the old geo index again. So you have to update the index manually after the updates again!
