when i click on "university" tabs it needs to open sub tabs like b.tech , mtech, phd,....  under university tabs list must open in a tab format and i click on b,tech and add colleges to it

I have a custom description field that is text long (3200).  Is it possilbe to filter on this field using dynamic soql?

strSOQL = 'Select Name, Event_Date__c, Description__c From SFDC_Event__c Where Description__c like ' + keywordString;
EList = Database.query(strSOQL);

If not, are there any workaround suggestions?

Thanks for any help.

Regards.
