Internally lucene allocates an array of the size n (searcher.search(query,n)) even if your query only returns 1 document. This causes the OOM. Only get as many results as you need! In turn is iterating and loading of all those documents necessary? What is your usecase of lucene where you have to load 30k of documents? You have to be aware of that if you load 30k docs you need enough memory for them in you JVM. I have no idea how you index and what you store in the index but 30k pdf with -Xmx128M is not much :)
