Hi Ganesh,
I have already tried my own comparator, below is my code :
SortComparator comparator = new SortComparator() {
@Override
protected Comparable getComparable(String arg0) {
final String str = arg0;
Comparable comparable = new Comparable() {
@Override
public int compareTo(Object o) {
System.out.println("obj = "+o.getClass()+",
str = "+str);
return
o.toString().compareToIgnoreCase(str);
}
};
return comparable;
}
};
SortField sortField = new SortField("110_a_t", comparator);
Sort sort = new Sort(sortField);
org.apache.lucene.search.Hits
catalogueHits=search.indexSearcher.search(query, sort);
-------------------------------------------------
here the lucene is passing the present class
(org.verus.ngl.lucene.search.NGLSearch$1$1) object to compareTo method, but
it is not a term to compare with anather term
so, how to implement the SortComparator, where should i change the code for
my comparator
Output :
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = Adalf Hitler
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = Adalf Hitler
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = agdfgdgdfg
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = agdfgdgdfg
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = afhuhruhgjr
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = afhuhruhgjr
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = afsfdsgsd
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = afsfdsgsd
obj = class org.verus.ngl.lucene.search.NGLSearch$1$1, str = adsadsd
Results are :
id = 134, docId = 105
id = 135, docId = 106
id = 102, docId = 73
id = 100, docId = 71
id = 101, docId = 72
id = 122, docId = 93
id = 127, docId = 98
id = 132, docId = 103
id = 143, docId = 114
