Hey Community.
I write my first component and now i got a problem hear is my code:
@Override
public void prepare(ResponseBuilder rb) throws IOException {
try {
rb.req.getParams().getBool("topoffers.show", true);
String client = rb.req.getParams().get("client", "1");
BooleanQuery[] queries = new BooleanQuery[2];
queries[0] = (BooleanQuery) DisMaxQParser.getParser(
rb.req.getParams().get("q"),
DisMaxQParserPlugin.NAME,
rb.req)
.getQuery();
queries[1] = new BooleanQuery();
Occur occur = BooleanClause.Occur.MUST;
queries[1].add(QueryParsing.parseQuery("ups_topoffer_" + client
+ ":true", rb.req.getSearcher().getSchema()), occur);
Query q = Query.mergeBooleanQueries(queries[0], queries[1]);
DocList ergebnis = rb.req.getSearcher().getDocList(q, null,
null, 0, 5, 0);
String[] machineIds = new String[5];
int position = 0;
DocIterator iter = ergebnis.iterator();
while (iter.hasNext()) {
int docID = iter.nextDoc();
Document doc =
rb.req.getSearcher().getReader().document(docID);
for (String value : doc.getValues("machine_id")) {
machineIds[position++] = value;
}
}
Sort sort = rb.getSortSpec().getSort();
if (sort == null) {
rb.getSortSpec().setSort(new Sort());
sort = rb.getSortSpec().getSort();
}
SortField[] newSortings = new SortField[sort.getSort().length +
5];
int count = 0;
for (String machineId : machineIds) {
SortField sortMachineId = new SortField("map(machine_id," +
machineId + "," + machineId + ",1,0) desc", SortField.DOUBLE);
newSortings[count++] = sortMachineId;
}
SortField[] sortings = sort.getSort();
for (SortField sorting : sortings) {
newSortings[count++] = sorting;
}
sort.setSort(newSortings);
rb.getSortSpec().setSort(sort);
} catch (ParseException e) {
LoggerFactory.getLogger(Topoffers.class).error( "Fehler bei den
Topoffers!", this);
LoggerFactory.getLogger(Topoffers.class).error(e.toString(),
this);
}
}
Why can't i manipulate the sort? Is there something i miss understand?
This search component is added as a "first-component" in the solrconfig.xml.
Please can anyone help me??
