Dear List,
I have two questions about indexing
*Question 1*
At the time of creation, we can use extra configuration can be specified to
control the behavior of the index and which backend to use.
e.g,
IndexManager index = graphDb.index();
Index<Node> movies = index.forNodes( "movies-fulltext",
MapUtil.stringMap( IndexManager.PROVIDER, "lucene", "analyzer",
"org.apache.lucene.analysis.cn.smart.SmartChineseAnalyzer" ) );
movies.add( theMatrix, "cTitle", "黑客帝国" );
movies.add( theMatrix, "date", "2000-01-01" );
When adding node "theMatrix" to index, all the values will be
analyzed/tokenized by SmartChineseAnalyzer.
However， for some fields I do not want it to be analyzed/tokenized, Any
interfaces to implement this? Can enhance valueContext so that I can pass
in something like Field.Index.NOT_ANALYZED when adding a node into index?
*Question 2*
For Query,
IndexHits<Node> nodes = movies .query(new BooleanQuery(...));
Node currentNode = null;
List<Movie> result = new ArrayList<Movie>();
while (nodes.hasNext()) {
currentNode = nodes.next();
Movie m = new Movie(currentNode);
if(m.getDate().equals("2001-01-01")){
result.add(m);
}
}
I found that if the indexHits is large, say size() > 20000, Each
m.getDate() will spend some time to load the value from underlying
node(especially the first-time query), So the total elapsed time is very
long.
Any interface that I can read the lucene document behind this node
directly? Maybe u can use nodes.currentDoc() to expose it?
Thanks and Regards,
Samuel
