While searching in Synergy, you will find that 15 result values is normal for many of the screens, before a new page needs to be selected. Every user can create their own unique number of search results to a single screen. Your particular values will not affect any other employees selections. Here are my thoughts:
1. On the CRM / Workflow / Documents / Items / Projects Search, keep the number down to no more than 500
2. In a workflow, I max out the number of fields when building them to the total available fields in the list. This saves me a lot of time while building the requests. Since I have our Free Fields tool, I keep them at 500 also.
When I need to do an export of data and wish to have them all displayed on the same page, I can set my limits much higher. However, I change the value back before I close out Synergy, so that I do not have any degradation of speed in my searches.
