Hi team,
The below code :
queryString = "piccadilly*";
Query queryToExecute = new StandardQueryParser().parse(queryString,
"stationNameIndex");
LuceneQuery<Long, Station> luceneQuery =
luceneService
.createLuceneQueryFactory()
.setLimit(100)
.create(
"stationNameIndex",
"stations-region",
index -> {
return new BooleanQuery.Builder()
.add(queryToExecute, BooleanClause.Occur.MUST)
.build();
});
Collection<Station> stations = luceneQuery.findValues();
*throws the below error : *
Error while querying => {}

whereas
LuceneQuery<Long, Station> luceneQuery =
luceneService
.createLuceneQueryFactory()
.setLimit(100)
.create(
"stationNameIndex",
"stations-region",
queryString,
"stationName"
});
works perfectly & Station implements org.apache.geode.DataSerializable.
What am I missing?.
Please help.
Regards,
Aj
