Phrase queries won't help you here....
Your particular issue can be addressed, but I'm not sure it's a
reasonable long-term solution....
If you indexed your address field as UN_TOKENIZED, and
did NOT tokenize your query, it should give you what you want.
What's happening is that StandardAnalyzer is indexing indivdual
tokens, not phrases. So, doc 1 has the tokens
"hiran", "margi"
Doc 2 has tokens.
"hiran", "magri", "sec", and "10"
and so on...
Searching, even for phrases, on "hiran margi" matches
4 docs because those two tokens appear next to each other.
If, on the other hand, you index your address field UN_TOKENIZED,
then doc1 has a "token" of "hiran margi", while doc 2 has a token
of "hiran magri sec 10". Doc2 won't match a query on
"hiran margi" etc.
But, this may not be a good solution because searching on
"hiran" won't match *any* document. You might have to index
the same fields two different ways to get all the behavior you
want.

Hello everyone,
I am lucene user and tried to implement pharse query, But now getting some
logical problems in searching..
My index have 4 fields: Name, Address & City and 6 docs.
i.e 1. "Laxmilal Menaria", "Hiran Magri", "Udaipur",
2. "Mohan Sharma", "Hiran Magri Sec 10", "Udaipur"
3. "Rohit Bhargav", "Suraj pole", "Udaipur"
4. "Laxmilal", "Hiran Magri Sec 4", "Ahemdabad"
5. "Chandresh" , "Bihar", "Patna"
6. "James", "Hiran Magri 18", "Delhi"
Now search Address:"Hiran Magri" and got 4 results, But I want 1 result
only(Document-1), so what should I do ?
My Search code is :
sQuery="Hiran Magri"
.
.
Dim lucQuery As Lucene.Net.Search.Query = New
Lucene.Net.QueryParsers.QueryParser("Address", New
Lucene.Net.Analysis.Standard.StandardAnalyzer).Parse(sQuery)
Dim lucHits As Lucene.Net.Search.Hits =
lucIndexSearcher.Search(lucQuery)
Dim intHitCount As Integer = lucHits.Length
