Description

I try to create a simple index and then update documents (with IndexWriter.updateDocuments). When I use RAMDirectory it works fine (IndexWriter.numDocs returns correct value, IndexSearcher.search returns correct hits). However, when I use FSDirectory it creates duplicate documents, and IndexSearcher returns multiple documents with same key field values. Here is the code excerpt:
//This code is in a thread and it updates documents with regular intervals, say 1 min.
Analyzer analyzer = new StandardAnalyzer();
try

{ Path path = Paths.get(indexDirectory); Directory directory = FSDirectory.open(path); IndexWriterConfig config = new IndexWriterConfig(analyzer); IndexWriter iwriter = new IndexWriter(directory, config); System.out.println("Document count=" + iwriter.numDocs()); for (Company newCompany : newCompanies) { Document doc = new Document(); doc.add(new Field("entityid", "Company" + newCompany.getId().toString(), TextField.TYPE_STORED)); doc.add(new Field("companyname", newCompany.getName(), TextField.TYPE_NOT_STORED)); Term term = new Term("entityid", "Company" + newCompany.getId().toString()); iwriter.updateDocument(term, doc); }

iwriter.flush();
iwriter.commit();
System.out.println("Document count2=" + iwriter.numDocs());
iwriter.close();
} catch (IOException e1)

{ e1.printStackTrace(); }
