I'm confused by some behavior I'm seeing in Solr (i'm using 1.2.0). I
have a field named "description", declared with the following
fieldType:
<fieldType name="textTightUnstemmed" class="solr.TextField"
positionIncrementGap="100" >
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="false"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="0" generateNumberParts="0" catenateWords="1"
catenateNumbers="1" catenateAll="0"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
The problem I'm having is that when I search for description:deck*, I
get the results I expect; when I search for description:Deck*, I get
nothing. I want both queries to return the same result set. (I'm using
the standard request handler.)
Interestingly, when I search for description:Deck from the web
interface, the debug output shows that the query term is converted to
lowercase:
<str name="rawquerystring">description:Deck</str>
<str name="querystring">description:Deck</str>
<str name="parsedquery">description:deck</str>
<str name="parsedquery_toString">description:deck</str>
... but when I search for description:Deck*, it shows that it is not:
<str name="rawquerystring">description:Deck*</str>
<str name="querystring">description:Deck*</str>
<str name="parsedquery">description:Deck*</str>
<str name="parsedquery_toString">description:Deck*</str>
What am I doing wrong here?
Also, when I use the Field Analysis tool for description:Deck*, it
shows the following (sorry for the bad copy/paste):
Query Analyzer
org.apache.solr.analysis.WhitespaceTokenizerFactory {}
term position 1
term text Deck*
term type word
source start,end 0,5
org.apache.solr.analysis.SynonymFilterFactory {synonyms=synonyms.txt,
