Subject [jira] [Updated] (LUCENENET-486) Wildcard queries are not analyzed
Date Thu, 19 Apr 2012 09:31:03 GMT

     [ https://issues.apache.org/jira/browse/LUCENENET-486?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Björn updated LUCENENET-486:
----------------------------

    Description: 
The lucene 'QueryParser' doesn't analyze wildcard querys. The function 'GetPrefixQuery'(QueryParser.cs)
returns the string without any analyzation.

I have performed some queries to show the problem. The analyzer is the 'Contrib.Analyzers.DE.GermanAnalyzer'

---------- indexed word: 'Häuser'; in the index stemmed as: 'hau' ----------

query: Hau*; hit: yes
query: Hause*; hit: no; This should be a hit.....


---------- indexed word: 'Angebote'; in the index stemmed as: 'angebo' ----------

query: Angebo*; hit: yes
query: Angebot*; hit: no; This should be a hit.....
query: Angebote*; hit: no; This should be a hit.....

---------- indexed word: 'Björn'; in the index stemmed as: 'bjor' ----------

query: Bjor*; hit: yes
query: Björ*; hit: no; This should be a hit.....
