Question

I have an existing index with some documents I’m trying to search.
When I search a “real textual” field, everything is OK.
When I try to search a field which is a number, the search gives 0 results.
The code is something like this (it is pylucene but the concept is the same):

dir = SimpleFSDirectory(File(indexDir))
analyzer = StandardAnalyzer(Version.LUCENE_CURRENT)
searcher = IndexSearcher(dir)
query = QueryParser(Version.LUCENE_CURRENT, "id", analyzer).parse("902")
hits = searcher.search(query, MAX)
print hits.totalHits #gives me 0

a luke search (id:902) gives me empty results as well.
When I look at the Overview tab on luke it says this field is UTF-8 (string)

Anything I’m doing wrong?

edit:
It appears this happens on Fields that are indexed and has no Norm (according to the flags of luke).
Can someone explain it?

Answer 1

I don’t like answering my own questions but I believe this answer is an important reference.
The solution is put a NumericRange query with both numbers the number you seek (this time in java):

NumericRangeQuery.newIntRange("id", Integer.valueOf(902), Integer.valueOf(902),
true, true)
