Code Ferret reassigned JENA-1652:
---------------------------------
Assignee: Code Ferret (was: Osma Suominen)
> jena-text analyzer regression
> -----------------------------
>
> Key: JENA-1652
> URL: https://issues.apache.org/jira/browse/JENA-1652
> Project: Apache Jena
> Issue Type: Bug
> Components: Text
> Affects Versions: Jena 3.10.0
> Environment: Ubuntu 16.04
> java version "1.8.0_191"
> Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
> Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
> Reporter: Osma Suominen
> Assignee: Code Ferret
> Priority: Major
> Fix For: Jena 3.10.0
>
>
> I noticed that Skosmos unit tests are failing when run with Fuseki 3.10
> snapshots:
> https://github.com/NatLibFi/Skosmos/issues/828
> Digging a bit deeper, it seems that jena-text is no longer applying the
> analyzer on query strings as it used to in 3.9.0. The most likely reason for
> this change seems to be the Lucene upgrade (JENA-1621) which may have
> affected how analyzers are applied.
> Here is the text analyzer configuration I'm using:
> {noformat}
> <#indexLucene> a text:TextIndexLucene ;
> ##text:directory <file:/tmp/lucene> ;
> text:directory "mem" ;
> text:entityMap <#entMap> ;
> text:storeValues true ;
> .
> <#entMap> a text:EntityMap ;
> text:entityField "uri" ;
> text:graphField "graph" ; ## enable graph-specific indexing
> text:defaultField "pref" ; ## Must be defined in the text:map
> text:uidField "uid" ;
> text:langField "lang" ;
> text:map (
> # skos:prefLabel
> [ text:field "pref" ;
> text:predicate skos:prefLabel ;
> text:analyzer [ a text:LowerCaseKeywordAnalyzer ] ]
> # skos:altLabel
> [ text:field "alt" ;
> text:predicate skos:altLabel ;
> text:analyzer [ a text:LowerCaseKeywordAnalyzer ] ]
> # skos:hiddenLabel
> [ text:field "hidden" ;
> text:predicate skos:hiddenLabel ;
> text:analyzer [ a text:LowerCaseKeywordAnalyzer ] ]
> ) .
> {noformat}
> Here is a minimal test file that I load into the default graph:
> {noformat}
> <http://example.org/guppy> <http://www.w3.org/2004/02/skos/core#prefLabel>
> "Guppy"@en-gb .
> {noformat}
> This is the query I'm using:
> {noformat}
> PREFIX text: <http://jena.apache.org/text#>
> SELECT * {
> ?s text:query 'G*' .
> }
> {noformat}
> It returns one row (?s=<http://example.org/guppy>) on Fuseki 3.9.0 but
> nothing with today's 3.10 snapshot.
> If I change the 'G*' to lowercase 'g*' then I get the expected match also
> with the 3.10 snapshot. So the analyzer (which should lowercase everything
> and thus the case of the query string should be irrelevant) seems not to be
> applied for the query string.
