Erik,
I managed to process the tokenStream further but it
does not allow to search for "host defense"
as phrase.
Here is what I've done:
(input to the function is by the string array myquery
which contains e.g. myquery[1]="term1",
myquery[2]="host defense")
BooleanQuery query = new BooleanQuery();
//for each term to add:
for (int j=0; j<myquery.length; j++){
stream = analyzer.tokenStream("contents", new
StringReader(myquery[j]));
String str = "";
while (true){
Token token = stream.next();
if (token == null) break;
str = str + token.termText() + " ";
}
query.add(new TermQuery(new Term("subject",
str.trim())), false, false);
}
With this code I tried to assemble single tokens like
"host" and "defense" that are probably coming out of
the analyser back to "host defense" - but it doesn't
find me "host defense" ??
