I would understand if you had said that "Klostermeyer*" returned nothing
because the presence of the wildcard used to suppress analysis, including
the lower case filter so that the capital "K" term would never match an
indexed term. But, I would have expected "klostermeyer*" to match
"klostermeyer" since the unanalyzed wildcard prefix would have the same
term value as "klostermeyer" when it is indexed. So, this is a mystery to
me.

Subject: Wildcard queries on whole words
I am researching an issue w/ wildcard searches on complete words in 3.5.
For example, searching for "kloster*" returns "klostermeyer", but
"klostermeyer*" returns nothing.
The field being queried has the following analysis chain (standard
'text_general'):
<fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true" />
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
I see that wildcard queries are not analyzed at query time, which could be
the source of my issue, but I read conflicting advice on the interwebs. I
read also that this might have changed in 3.6, but I am unable to determine
if my specific issue is addressed.
My questions:
1. Why am I getting these search results with my current config?
2. How do I fix it in 3.5? Would upgrading to 3.6 also "fix" my
issue?
Thanks!
