Hi,
My company policy not allowed me to place files on websphere server JVM, so
thats why we are placing index files in database and searching using
JDBCDirectory.
I am using 2.4 Lucene API jars API with below ways to search the fields
from index,
Directory dir; = new JdbcDirectory (ds,dialect, indexFileName,true);
Searcher searcher = new IndexSearcher(dir);
Hits hits = searcher.search(searchQuery);
for (int i = 0; i < hits.length(); i++) {
Document doc = hits.doc(i);
if(doc.get("Name") != null && !"".equals(doc.get("Name"))){
....other biz logic
}
}
Thanks
Mahesh
