Hi,
It is not the problem with case..Because Iam using LowercaseFilter.
My Analyzer is a custom analyzer which will ignore just white spaces.All
other numbers date and other special characters it will consider.The Same
analyzer works for Lucene 3.6.
When i do a single term query for "Geoffrey" it is giving hits..But when
given as a part of multiphrase query ,it is not able to find..When the
below code is Executed with say word ="Geoffrey",it is not finding the word
itself ..
if(TermsEnum.SeekStatus.FOUND ==trm.seekCeil(new BytesRef(word)))
{ do {
String s = trm.term().utf8ToString();
if (s.equals(word)) {
termsWithPrefix.add(new Term("content",
s));
} else {
break;
}
}
while (trm.next() != null);
}
