My first guess would be maybe the german stemmer, or some other part of the german analyser pipeline is changing the word? Do you get the same result if you put "content" in the contents field? E.g.

+(+(contents:con*)) +__IndexType:con

Tim,

No if you type word content you get

{ SearchIndexType: content, LuceneQuery: +(+(contents:content*)) +__IndexType:con }

Something else is borking it GRRRR

Tim,

Actually you are right. So we took of the wildcard then did query again and now we get

"{ SearchIndexType: content, LuceneQuery: +(+(contents:con)) +__IndexType:con }"

Rats!!

Tim,

Very interesting read http://www.evelix.ch/unternehmen/Blog/evelix/2013/11/11/inner-workings-of-the-german-analyzer-in-lucene could be the stemmer mashing it up. Says if word is wildcarded then its not stemmed.

So maybe this is the issue.

This stack overflow post might have some clues, it looks like in the Java version at least, you can specify words that don't get stemmed. Not sure if that's the case in the .Net port though.

Tim,

Its definately the stemmer, I have opened luke and in the plugins section done some analysis and for word content using german analyser you get stemmed form content.

Tim,

My colleague Dawid has created an issue on github https://github.com/Shazwazza/Examine/issues/54

I've created a pull request for this issue in Examine repo:

A workaround for this to modify the query text, after query is being compiled (so tokenized and stemmed by GermanAnalyzer).

 var rawQuery = query.Compile().ToString();

 var queryMatch = Regex.Match(rawQuery, 
      @"LuceneQuery: (?<query>.*?)\s*}$");

 var luceneQueryText = queryMatch.Groups["query"].Value;

 var fixedRawQuery = Regex.Replace(
        luceneQueryText, 
        "__IndexType:con$", 
        "__IndexType:content*");

 var fixedCriteria =  contentSearcher.CreateSearchCriteria();

 fixedCriteria.RawQuery(fixedRawQuery);

 var contentSearchResults = contentSearcher.Search(fixedCriteria);

is working on a reply...
