ignore it, ES needs restart after plugin installation

[chief]

ok thanks

[mbouclas]

if the plugin works, would it work with accents? For example search for φρα would it be equal to φρά? Cause in my searched it doesn't work.

Thanks

Input is expected to to be casefolded for Greek (including folding of final sigma to sigma), and with diacritics removed. This can be achieved with GreekLowerCaseFilter.

[mbouclas]

are you refering to an ES filter or JAVA class?

[chief]

ES filter

[chief]

Please have in mind that we do not test our plugins with new elasticsearch (>1.0.0) (currently we support up to 0.90.3).

[mbouclas]

so what you mean is something like "filter" : ["myGreekLowerCaseFilter","stem_greek"] where myGreekLowerCaseFilter is "myGreekLowerCaseFilter": { "type": "lowercase", "language" :"greek" }

[chief]

seems good to me.

Thanks a lot, it works fine now
