Methods Summary
protected void	addDocument(org.apache.lucene.index.IndexWriter writer, java.lang.String id, java.lang.String text) Adds the document to the index. param writer the Lucene index writer param id the unique id of the document param text the text of the document throws IOException final Document document = new Document(); document.add(new Field(FIELD_ID, id, Field.Store.YES, Field.Index.UN_TOKENIZED)); document.add(new Field(FIELD_TEXT, text, Field.Store.YES, Field.Index.TOKENIZED)); writer.addDocument(document);
protected void	assertHits(org.apache.lucene.search.Hits hits, java.lang.String description, java.lang.String[] expectedIds, float[] expectedScores) Checks to see if the hits are what we expected. param hits the search results param description the description of the search param expectedIds the expected document ids of the hits param expectedScores the expected scores of the hits throws IOException // display the hits /*System.out.println(hits.length() + " hits for search: \"" + description + '\"'); for (int i = 0; i < hits.length(); i++) { System.out.println(" " + FIELD_ID + ':' + hits.doc(i).get(FIELD_ID) + " (score:" + hits.score(i) + ')'); }*/ // did we get the hits we expected assertEquals(expectedIds.length, hits.length()); for (int i = 0; i < hits.length(); i++) { assertTrue(expectedIds[i].equals(hits.doc(i).get(FIELD_ID))); assertEquals(expectedScores[i], hits.score(i), 0); }
