Hi Guys
Finally with lot's experimentation, I came to know that
A word such as 'new' already present in Analyzer,
will not return any hits [ Even when enclosed with Quotes "\""]
such as "New Year"....
That's really Intresting.... :(
That's why it's call stop word *removal*. The purpose of removing words is to save space and eliminate words that are ultra common. Tuning the analysis process to your domain/environment is by far the trickiest part of using Lucene, and often is not even much of a consideration as the built-in Analyzers suffice. It sounds to me that your stop word list is far too aggressive and you should consider trimming down the list of words that are removed.
Or, even consider not removing words at all. From the What Would Google Do (WWGD)? category.... does Google remove stop words? I'll leave that as a rhetorical question for now :)

Thx Karthik

[ The Analyzer I use has 555 English Stop words with "new" present in it ]
No wonder!
That's when I checked up with Analyzer's to verify, If u look at the list Analyzer's o/p GrammerAnalyzer is the one that has 555 English STOPWORDS.
Do u think this is the bug in my Code.
Whether this is a "bug" or not is really for your users to determine :) But it is absolutely the expected behavior. QueryParser analyzes the expression too. Even if you somehow changed QueryParser, if you never indexed the word "new" then you certainly cannot expect to search on it and find it.
