Hello
about 3 months ago I posted some idea about wildcard searching.
main idea was to index every character of input as separate term. and
then search using PhraseQuery.
for example word "12345" would be indexed as "1" "2" "3" "4" "5". to
find "*23*" you can use PhraseQuery with this two term

Actually, the problem is that the wildcard code has to search over a large
subset of terms because the list of terms is, well, a linear structure.
If, for example, all terms in the index is arranged as a suffix

way to do this?
Sure. Simply index reversed words.
The reason why QP prohibits wildcards at the beginning is perfor
