LengthFilter may generate a TokenStream where first token has
positionIncrement==0
----------------------------------------------------------------------------------
Key: LUCENE-1253
URL: https://issues.apache.org/jira/browse/LUCENE-1253
Project: Lucene - Java
Issue Type: Bug
Components: Analysis
Affects Versions: 2.3.1
Reporter: Walter Ferrara
Priority: Minor
See for reference:
http://www.nabble.com/WordDelimiterFilter%2BLenghtFilter-results-in-termPosition%3D%3D-1-td16306788.html
and http://www.nabble.com/Lucene---Java-f24284.html
It seems that LengthFilter (at least) could produce a stream in which the first
Token has a positionIncrement of 0, which make CheckIndex and Luke function
"Reconstruct&Edit" to generate exception.
Should something be done to avoid this situation, or could the error be ignored
(by allowing Term with a position of -1, and relaxing CheckIndex checks?)
