Arcadius Ahouansou updated LUCENE-6680:
---------------------------------------
Attachment: LUCENE-6680.patch
Initial patch fixing the comparator to take into account the payload when
everything else is same.
> BlendedInfixSuggester dedup bug
> -------------------------------
>
> Key: LUCENE-6680
> URL: https://issues.apache.org/jira/browse/LUCENE-6680
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 5.2.1
> Reporter: Arcadius Ahouansou
> Attachments: LUCENE-6680.patch
>
>
> I expect the following test to pass, but it's failing in the latest Lucene
> 5.2.1:
> {code:title=FailingTest.java|borderStyle=solid}
> public void testBlendedInfixSuggesterDedupsOnWeightTitleAndPayload() throws
> Exception {
> //Only the payload is different
> Input[] inputDocuments = new Input[]{
> new Input("lend me your ear", 7, new BytesRef("uid1")),
> new Input("lend me your ear", 7, new BytesRef("uid2")),
> };
> Analyzer a = new MockAnalyzer(random(), MockTokenizer.WHITESPACE, false);
> BlendedInfixSuggester suggester = new
> BlendedInfixSuggester(newDirectory(), a, a,
> AnalyzingInfixSuggester.DEFAULT_MIN_PREFIX_CHARS,
> BlendedInfixSuggester.BlenderType.POSITION_RECIPROCAL, 10, false);
> InputArrayIterator inputArrayIterator = new
> InputArrayIterator(inputDocuments);
> suggester.build(inputArrayIterator);
> List<Lookup.LookupResult> results =
> suggester.lookup(TestUtil.stringToCharSequence("ear", random()), 10, true,
> true);
> suggester.close();
> a.close();
> assertEquals(2, results.size());
> }
> {code}
> This test is failing because the BlendedInfixSuggester internally uses a
> TreeSet for storing the results and the corresponding Comparator only uses
> text+weight meaning that results with different payloads are collapsed into
> one.
> The point here is that if two ingested documents have same title, weight but
> different payloads, then they are two different things and folding them into
> a single document would mean loosing the payload information
