Yes, there is a Caveat that if some words are removed from the database then you will need to reindex for that to be taken into account. However, in the case of bug tracking (which is largely what we are doing), data tends to be added rather than removed. Plus re-indexing happens on a project bases, not a global basis. Also, for our use case it is not necessarily a bad thing that removed words may cause an item to be shown in the results. After all, just because a paragraph was removed from a bug description doesn't necessarily mean it is invalid search fodder (bearing in mind that, in our case, full-text search is just one way of filtering).
