Hi,
I am using the PorterStemAnalyzer class (attached) to provide stemming
for a Lucene index.
To stem the terms in the index we use the following...
//open an index writer in append mode
IndexWriter idxWriter = new IndexWriter(LUCENE_INDEX_PATH, new
PorterStemAnalyzer(), false);
//add the lucene document to the index
idxWriter.addDocument(idxDoc);
Having inspected the index using Luke, I can confirm that the terms are
being stemmed as expected. However, in order for this to work properly I
am not clear whether I should also be stemming the search terms that are
entered?
For example there is a term "relax" in the index which I guess is
stemmed from "relaxation". If the user searches on "relaxing" do I need
to stem the search term in order for it to return the result?
At the moment I am attempting to do this as follows...
analyzer = new PorterStemAnalyzer();
parser = new QueryParser("content", analyzer);
Query query = parser.parse("keywords: relaxing");
Hits hits = idxSearcher.search(query);
...but this is not returning any matches.
Thanks
