Re: newbie question (for John Griffin) - fixed

[Chris Bamford]

Hi John

Thanks for your continued interest in my travails!
==I'm not sure I understand. You want a phrase query so they should be
==passed as a phrase in quotes.

Ok... well I must be missing something then  :-(
This fails to return any hits for me:

       PhraseQuery pq = new  PhraseQuery();       
       pq.add(new Term("body", "aaa ddd"));

while
      PhraseQuery pq = new  PhraseQuery();       
      pq.add(new Term("body", "aaa"));
      pq.add(new Term("body", "ddd"));

works fine.
I have tried with both Lucene 2.0 and 2.3 jars.

Please advise!

Thanks,

-Chris
   BTW thanks for the tip about Luke

Hi John,

Please ignore my earlier questions on this subject, as I have got to the 
bottom of it.
I was not passing each word in the phrase as a separate Term to the 
query; 

==I'm not sure I understand. You want a phrase query so they should be
==passed as a phrase in quotes.


instead I was passing the whole string (doh!).

Thanks.

Hi John,

Further to my question below, I did some back-to-basics investigation 
of PhraseQueries and found that even basic ones fail for me...
I found the attached code on the Internet (see 
http://affy.blogspot.com/2003/04/codebit-examples-for-all-of-lucenes.html)
    

  
and this fails too...  Can you explain why?  I would expect the first 
test to deliver 2 hits.

I have tried with Lucene 2.0 and 2.3.2 jars and both fail.

Thanks again,

- Chris

Hi John,

Just continuing from an earlier question where I asked you how to 
handle strings like "from:fred flintston*" (sorry I have lost the 
original email).
You advised me to write my own BooleanQuery and add to it Prefix- / 
Term- / Phrase- Querys as appropriate.  I have done so, but am having 
trouble with the result - my PhraseQueries just do not get any hits 
at all  :-(
My code looks for quotes - if it finds them, it treats the quoted 
phrase as a PhraseQuery and sets the slop factor to 0.
so,  an input of:

   subject:"Good Morning"

results in a PhraseQuery (which I add to my BooleanQuery and then 
dump with toString()) of:

   +subject:"good morning"

... which fails.
However, if I break it into 2 TermQuerys, it works (but that's not 
what I want).

What am I missing?

Thanks,

- Chris
