>> is a rex operator. If you want the phrase "central database" put quotes around it in the query. If you're using likep and turn up likeporder it will rank items with the words in order higher.
there may be words in between central and database which would not render the hit irrelevant, which is why I am using a proximity of w/2. So having central side by side with database is not an option. We are using the like operator and I have no ability to change it becuase I am performing the search through an application. Using rex is ok, as long as I get correct results. From my testing, it seems I am not specifying the phrase correctly. What else do you suggest?
