Background:
We created a couple of custom fields in outlook/exchange and set up Enterprise Vault to index them as well. These searchable fields make it a lot easier to find a specific message after a couple of years. We also used a keyword - type field, and the keywords were basically just outlook categories that got assigned via a custom interface in outlook. EV indexes the categories field by default. So far so good, and we were happy with the way things worked.
After upgrading to exchange/outlook 2007 we started running into some problems with quick-click option on categories (where it helpfully deletes keywords you have assigned if you want to or not). We would like to store our keywords now in another custom field, and index that as well BUT we would like to have the EV search functionality search both categories and our new 'keywords' field at the same time. This would mean the end users can just type in the keywords into the same search field, but that it would find both old and newer messages that have keywords stored in a different field.
Question:
So, is it possible to point one field on the web search form to 2 different indexed fields (of the same type - comma seperated string values) or to somehow copy the indexes created for categories on the old messages to the new "keywords" field and then just search on the the new field to find both the new and older messages?
