Hi!

As per jira-LUCENE-7932 discussions I am sending this mail along with my java code(LuceneQueryTest.java class: attached) calling Lucene code.


A.      Code structure:
Attached sample code(LuceneQueryTest.java class) consists of 4 steps:

1.       Create index (Needed to be executed only once to insert records)

2.       Prepare query parameters

3.       Prepare QueryParser object

4.       Search and display results



B.      Analysis Report:

Step 1 can be executed only once because it creates index files first time and then it can be commented.

Step 2 has 3 cases

Case a) queryParams = "LocationCode:1 AND Category:a";

                Test analysis: When we execute this query all records are fetched, even though we don't have records of Category=a. (Not working)

                [cid:image001.png@01D32304.5139F330]



Case b) queryParams = "LocationCode:1 AND Category:A";

                Test analysis: When we execute this query all records are fetched, even though we don't have records of Category=A. (Not working)

[cid:image002.png@01D32304.5139F330]



Case c) queryParams = "LocationCode:1 AND Category:a*"; (Works Fine)

                Test analysis: When we execute this query No records are fetched, this works fine.

                [cid:image003.png@01D32304.5139F330]

C.      Submission to lucene development team:

Looking at case a) and case b) I think there is bug in Lucene IndexSearcher.java or IndexReader.java in LuceneCore module.

I used both Lucene 5.3 and latest version Lucene 6.6 to reproduce issue. I found same results.



If you need more information, please let me know.
