Hi,
I am new to neo4j.
I am using a custom analyzer in index in order to support Chinese.
chnIndex = this.graphDb.index().forNodes("product_chinese",
MapUtil.stringMap("analyzer",
"org.wltea.analyzer.lucene.IKAnalyzer"));
Below is the usage of the IKAnalyzer in lucence.
IndexSearcher isearcher = new IndexSearcher(directory);
isearcher.setSimilarity(new IKSimilarity()); // A custom Similarity
String word = "OLYMPUS 奥林巴斯 E-PL1 时尚白 微型4/3系统相机 套机 含14-42mm镜头";
Query query = IKQueryParser.parse(fieldName, word ); // A custom
QueryParser
TopDocs topDocs = isearcher.search(query, 5); // Got the top 5
System.out.println("Found " + topDocs.totalHits);
ScoreDoc[] scoreDocs = topDocs.scoreDocs;
for (int i = 0; i < topDocs.totalHits; i++) {
System.out.println(scoreDocs[i].score); // Got the score of each
matched doc
Document targetDoc = isearcher.doc(scoreDocs[i].doc);
System.out.println("Document content is " + targetDoc.toString());
}
How can I use the query method of neo4j's indexing to implement
1) Add my custom Similartiy implemtation
2) The TopDocs interface can replaced by the iterator of IndexHits, right?
3) Possible to get the score for each node in the IndexHits?
Thank you for the help and time spent on this.
Samuel
