Re: problem executing a query using lucene directly
Solr wraps its IndexReader in an UninvertingReader, which builds doc-values
structures in memory if required. If you include the solr jar file on your
classpath, you should be able to use UninvertingReader.wrap() to do something
similar.

Re: problem executing a query using lucene directly
Hi Alan,
thank you very much, but I am not sure if this is the reason.
but if I use the solrSearcher, FieldValueQuery works well, using the same
index.
If SolrIndexSearcher enable this feature, how does it do it?
Thank you again!

Re: problem executing a query using lucene directly
Hi,
FieldValueQuery reports matches using docvalues, and it looks like they’re not
enabled on that field.

You're writing Lucene code here. A large part of Solr's purpose is to
avoid the need for Lucene code, so only a fraction of the people on this
list know how to write and troubleshoot Lucene code. I am not one of them.
You may have better luck with the java-u...@lucene.apache.org mailing
list. Your question is off-topic for this list.

problem executing a query using lucene directly
Hi all,
I have created an index using solr. I am trying to execute the following
code, but I get zero results in the count.
DirectoryReader dr = DirectoryReader.open(FSDirectory.open(new
File(indexDir).toPath()));
IndexSearcher searcher = new IndexSearcher( dr );
System.out.println(dr.maxDoc()); // Shows 200
Query query = new FieldValueQuery("table");
CollectionStatistics stats = searcher.collectionStatistics("table");
System.out.println(stats.docCount()); // Shows 200
System.out.println(searcher.count(query)); //Shows 0, should be 200
The definition of the table filed in the schema.xml is:
Any idea, why this could be happening? Why the search with the
FieldValueQuery is not returning the correct result?
Thank you very much in advance.
