Re: FuzzyQuery- why is it ignored?

i still cannot find the reason why MAINS cannot be found by the Lucene index with StandardAnalyzer. MAINZ, MAINK, MAINT all works ok. Any suggestions please? Best regards On 6/16/19 9:38 AM, Baris Kazar wrote: Tomoko,- Yes, i noticed that last nite when i was researching it and

A possible Java exception message fix

Index created with Lucene 6.6 and according to that,  this error message might need update:-> This version of Lucene only supports indexes created with release 7.0 and later. The first part of the error message is consistent with the error: -> 6 (needs to be between 7 and 9). Hope this helps

StanardFilter Question : https://issues.apache.org/jira/browse/LUCENE-8356

According to this jira ticket, where else is StandardFilter included in Lucene 8.1.1? and why is it a no-op now in Lucene 8.1.1? I wish the tickets were a bit more explicit and suggest what to use instead for deprecated versions like in version 7.5.0 or why it became no-op in version 8.1.1?
