How to get number of optimzed fields

Question

hi Experts,
I am using ecm11.1.1.0.5 on linux with oracle 11g, I added some information fields with ecm console and did a complete index rebuild, while ecm told me I have excessed limitation of optimized field number, I checked the doc, and found the following limitation:
Oracle Content Server system can have up to 32 Optimized Fields, which includes data, integer, standard Oracle Content Server fields like dInDate, dOutDate, and fields selected to be optimized. All Optimized Fields are SDATA fields, which by default include dDocName, dDocTitle, dDocType, and dSecurityGroup.
I checked my optimized fields from ecm console again(administration->admin applets->configuration manager->information fields->advanced search design)
I found 12 fields defined as isinSearchResult and isOptimized, 8 fields defined as isInSearchResult and IsSortable, then why I excessed limitation of 32 optimized field?
Another question is:
Is there a way for me to add fields with searchable and search in result function but without full rebuild index?
Search engine is oracle text.
Best regards
Lan

So now I've had a bit of sleep and some caffeine, let me go a bit deeper.
When you mark a field as "indexed/searchable" in Configuration Manager, if the field is an integer field or a date field, when OTS is the search engine, that field is assigned to a SDATA section. There is a limit of 32 SDATA fields using OTS 11g. That is NOT to say you cannot have more than 32 date and or integer fields, but [searchable date fields] + [searchable integer fields] + [declared optimized fields] cannot exceed a total of 32.
Should you need more date and integer fields, you can add them, but you simply cannot index them for seaching purposes.
URM is a good example of this, as it uses a LOT of date fields. The installer detects if the search engine is OTS, and does not mark its date fields as searchable if OTS is indeed the search engine.
