Enabling the index table engine
If you read the previous chapters, you should have the index table generated and ready to use. To make use of it, open up the search instance(s) you wan't to use it with, and change the first option that appears:
Save the options, and that's it. This search instance will use the index to look for keywords.
If you don't have an index table generated, go to the previous chapter to see how it's done.
