Range query with Lucene7.7.1 on old indexes.

[Antony Joseph]

Hi all,

Using: python 2.7.14, pylucene 4.10.0

Index:

xdate = long("20190101183030")
doc.add(LongField('xdate', xdate, Field.Store.YES)) # stored and not
analyzed

Query:

query = NumericRangeQuery.newLongRange("xdate", long("20190101000000"),
long("20190101115959"), True, True)

I am getting the results. It works fine.

Now i upgraded the lucene index 4.10.0 to lucene 7.7.1

Using : Python3.8.11, pylucene 7.7.1

I am searching on my old indexes, using the following queries

query = NumericDocValuesField.newSlowRangeQuery("xdate",
long("20190101000000"), long("20190101115959"))

No results.

query = LongPoint.newRangeQuery("xdate", long("20190101000000"),
long("20190101115959"))

No results.

How to get the results on my old indexes using date range query?

Can anyone help?

Thanks
