Re: Phrase Query

[Hetan Shah]

What I am trying to do is to create the query based on the field in 
which user enters the keywords.

I have the following fields.
All the Words:
The Exact Phrase:
Any of the Words:
For All the words and Any of the words I am able to use Query. For The 
Exact Phrase I want to use the PhraseQuery. That is what I was showing 
in the code snippet. My mistake in not commenting out the line where I 
was per-pending and appending the quotation marks, which is taken care 
by  the PhraseQuery. So how would one go about creating the different 
queries and then do the actual search.

Thanks.

Here is what I am striving to achieve.
phraseString =     request.getParameter("phrase");
if (phraseString.length() > 0){
    phraseQueryString = "\""+phraseString+("\"");
    phraseQuery = true;
    queryString = phraseQueryString;
}
if(phraseQuery){
    PhraseQuery pQuery = new PhraseQuery();
    pQuery.add(new Term("contents", phraseString));
    pQuery.setSlop(0);
    QueryParser qP = new QueryParser();
    query = qP.parse(phraseString);
}

I don't understand what you're attempting in the above.  You don't make 
a new Term and add it to a PhraseQuery instance with the term having 
quotes around it - it is QueryParser that deals with quoted strings and 
interpreting it into a PhraseQuery.

Are you using pQuery?  Or query?  You've got two Query instances there - 
query is the one you probably want.
