If leading wildcards take too much time (don't know, really) then one
could also try to index
ge-dependent/-specific.

You'd have to implement it separately but it'd be much, much smaller
than Lucene itself (even obfuscated).

Does it mean that the resulting index will be very large?

Hi,
I have a similar issue.
I need lucene search to work with kanji characters (japanese).
The hits object (or topDocs) returns length = 0 for results but works well
for english.
I know my index contains matches as luke (lucene search tool) renders them.
I tried lace analyser - did not work.

With NGramFilter you can do that. But it creates a lot of tokens. For example
"Fox is running fast" becomes
F
o
I can't speak for any non-Latin languages, but how about simply using the
StandardAnalyzer plus the EdgeNGramFilter for indexing (but not query.) The
latter would allow a query of "run" to match "running".

What you need is a suffix tree or a suffix array. Both data structures
will allow you to perform constant-time searches for existence/
occurrence of any input pattern. Depending on how much text you have
on the input it may either be a simple task -- see here:
