Rechecked my lucene index on Geode and they are as follows:
create lucene index --name=stationNameIndex --region=stations-region
--field=stationName,longitude,latitude
--analyzer=org.apache.lucene.analysis.en.EnglishAnalyzer,DEFAULT,DEFAULT
and in java code
queryString = "stationName: 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();
});
luceneQuery.findValues() throws Serialization exception but when I use the
LuceneQuery<Long, Station> luceneQuery =
luceneService
.createLuceneQueryFactory()
.setLimit(100)
.create(
"stationNameIndex",
"stations-region",
queryString,
"stationName"
});
It works.
What has gone wrong?
