I am not sure if I understand you. Do I add the terms for the second
phrase immediately after I add the terms for the first phrase. When do
i wrap the PhraseQuery I construct into a BooleanQuery.
For instance
String newTerm1= "avoids deadlock";
String newTerm2= "reduces cost";
PhraseQuery query =new PhraseQuery();
String[] phraseTerms1 = newTerm1.split( " ");
Term[] phrTerm1=new Term[phraseTerms1.length];
for(int u=0; u<phraseTerms1.length;u++)
{
phrTerm1[u]=new
Term("contents",phraseTerms1[u]);
query.add(phrTerm1[u]);
}
String[] phraseTerms2 = newTerm2.split( " ");
Term[] phrTerm2=new Term[phraseTerms2.length];
for(int u=0; u<phraseTerms2.length;u++)
{
phrTerm2[u]=new
Term("contents",phraseTerms2[u]);
query.add(phrTerm2[u]);
}
Hits hits = searcher.search(query);
The
code above just adds the terms of phrase2 following the
terms for phrase1.
Can you give me an example building a BooleanQuery OR for the
newTerm1 and newTerm2.
Thanks again
