IMO, a "reversed word Index" does not work in this case, because he's looking for a word in the middle (See curi*).
Another idea is to build word chunks and save them in a second index plus docID of the first index. e.g. security go to "security ecurity curity ... ity" This is much faster to search (just "curi*") but getting much bigger in index size. So it depends what is needed ...
