have the business logic and data access logic running on many machines, as shown in Figure 1-17. In fact, all three layers can be spread across multiple machines. It s not uncommon to use Web farms, load balancers, and database clusters to achieve optimal performance.

Figure 11 30. Activity search example 3. Click the activity line item in which you would like to request technical assistance.

Another nice addition to phpBB 3.0 s search facilities is a new section in the Administration panel that permits you to allocate a minimum and maximum size of the index, specify words you do not wish to be indexed, and re-create the search index. phpBB 2.0 did not permit you to do much work on this index, as it handled most of the operations itself. Now, if you wish to alter the search index for some reason (if it is getting too large for your liking, for example), you have the tools to work on it.
