phrase search with trailing wildcard

[catch22]

From what I can read on other forums it seems the answer to my question is "cant be done", but my brain simply wont accept that. The type of query I want to be able to perform is not of the type
"th* is n* pos*" matching ex. "this is not possible". I only need trailing wildcard, like "This is*" matching ex. "This is possible" or "This is not possible". Can this be behavior be simulated somehow, seing as it apparently isn't possible "out of the box" ?

You're suggesting I use the reqexQuery from lucene ?

This should be easy to do. Why not use a simple regular expression (regex) and the String matches method to test your Strings? The regex could be as simple as "This is.*" if case matters.

I guess I wasn't being clear on the scenario I'm facing. I have a lucene index with thousands of documents I need to search. Searching with the term "this is no" gives no hits even if I have a document with a field containing "This is not possible". I can't add * to the term.

You can create search term like:
String searchTerm = new String("This is"+"*");

It will be contains search and it will give us results having text 'This is possible' or 'This is not possible'.
