Hi,
I get it working..here is logic that need to implement...
In function getTermQuery check term is stop word or not if it is stop
word then return null.
Otherwise return SrndTermQuery object..
Code ...
protected SrndQuery getTermQuery(
String term, boolean quoted) {
if(stopwordList != null && stopwordList.contains(term))
return null;
return new SrndTermQuery(term, quoted);
}
Here stopwordList is static collection..
Next in each Query function (NQuery, NotQuery, AndQuery, WQuery) add
code as per following OrQuery
SrndQuery OrQuery() : {
SrndQuery q;
SrndQuery prevq = null;
ArrayList queries = null;
Token oprt = null;
}{
q = AndQuery()
( oprt = <OR> { /* keep only last used operator */
if (queries == null) {
queries = new ArrayList();
}
if(q != null)
queries.add(q);
prevq = q;
if(queries.size() >= 2){
q = getOrQuery(queries, true /* infix */, oprt);
return q;
}
}
q = AndQuery() {
if(q != null)
queries.add(q);
else
q = prevq;
if(queries.size() >= 2){
q = getOrQuery(queries, true /* infix */, oprt);
}
}
)*
{return q;}
}
Now generate QueryParser.java file using javaCC then do search..
Thanks,
Jagdish.
