No Umlauts returned

Question

Hi all,
Querying a table with ctx_doc.snippet doesn't return the german umlauts, so the results are not displayed correctly.
The data Storage is multicolumn datastorage, the current lexer is ctxsys.default_lexer.
The target of the query contains a clob with contains mostly html docs
Is there a way to prevent from hiding the umlauts?

Hello Barbara,
please excuse the late reply,
I've overseen this thread several times.
Here's a snippet of the output from ctx_report.create_index_script:
begin
ctx_ddl.create_preference('"IDX_DOCS_VOLLTEXT_DST"','DIRECT_DATASTORE');
end;
+/+
begin
ctx_ddl.create_preference('"IDX_DOCS_VOLLTEXT_FIL"','AUTO_FILTER');
end;
+/+
begin
ctx_ddl.create_section_group('"IDX_DOCS_VOLLTEXT_SGP"','AUTO_SECTION_GROUP');
end;
+/+
begin
ctx_ddl.create_preference('"IDX_DOCS_VOLLTEXT_LEX"','BASIC_LEXER');
ctx_ddl.set_attribute('"IDX_DOCS_VOLLTEXT_LEX"','MIXED_CASE','NO');
end;
+/+
begin
ctx_ddl.create_preference('"IDX_DOCS_VOLLTEXT_WDL"','BASIC_WORDLIST');
ctx_ddl.set_attribute('"IDX_DOCS_VOLLTEXT_WDL"','STEMMER','GERMAN');
ctx_ddl.set_attribute('"IDX_DOCS_VOLLTEXT_WDL"','FUZZY_MATCH','GERMAN');
end;
+/+
begin
ctx_ddl.create_stoplist('"IDX_DOCS_VOLLTEXT_SPL"','BASIC_STOPLIST');
I've compared to another Index and found out, that some attributes are different there:
ctx_ddl.set_attribute('"IDX_ZVVDATEN_LEX"','COMPOSITE','GERMAN');*
ctx_ddl.set_attribute('"IDX_ZVVDATEN_LEX"','MIXED_CASE','YES');*
ctx_ddl.set_attribute('"IDX_ZVVDATEN_LEX"','ALTERNATE_SPELLING','GERMAN');*
end;
+/+
I'll try to change the malfunctioning index to that.
Thanks for your hint,
regards
Franz
