lucene query special characters -


i have trouble understandnig handling of special characters in lucene.
analyzer has no stopwords, special chars not removed: 

chararrayset stopwords = new chararrayset(0, true); return new germananalyzer(stopwords);

than create docs like: 

doc.add(new textfield("tags", "23", store.no)); doc.add(new textfield("tags", "brüder-grimm-weg", store.no));

query tags:brüder\-g works fine, fuzzy query tags:brüder\-g~ not return anything. when street name eselgasse query tags:esel~ work fine.
use lucene 5.3.1

thanks help!

fuzzy queries (as wildcard or regex queries) not analyzed queryparser.

if using standardanalyzer, instance, "brüder-grimm-weg" indexed 3 terms, "brüder", "grimm", , "weg". so, after analysis have:

  • "tags:brüder\-g" --> tags:brüder tags:g
    matches on tags:brüder

  • "tags:brüder\-g~" --> tags:brüder-g~2
    since not analyzed, remains single term, , have no matches, since there no single term in index "brüder-g"
