Looks OK to me. You are searching on Item without adding any docs
with that field, you could use writer.updateDocument() rather than
delete and add, but those are just quibbles and don't explain your
searching problem.
Having done most of the hard work, why don't you adapt the code you
posted into a simple standalone program or test case that demonstrates
the problem. As simple as possible, no external dependencies, clearly
showing what you are indexing and what you are searching on, with one
search that works and one that doesn't.
One warning: using MultiFieldQueryParser with leading wildcards is
pretty much guaranteed to be slow on a large index.
