I try to get back a list of all left or right neighbours of a searchterm. Then I will count them to get back the Information, how often a specific word is used as neighbour of the searchterm. I know that the results are variable according to the used Analyzer/Filter. It's just an experiment and first I'll try to find out if it is possible to do something like that with Lucene.

In Lucene, you search with a term, you are not trying to get some. Basically, in Lucene, you have a list of term pointing on documents, not the reverse. Maybe if you explain why you are trying to do that, we can find a better way to do it.
