Search with facet.pivot

[Anders Dam]

Hi,

I have a minor problem in getting the pivoting working correctly. The thing
is that two otherwise equal search queries behave differently, namely one is
returning the search result with the facet.pivot fields below and another is
returning the search result with an empty facet.pivot. This is a problem,
since I am particularly interested in displaying the pivots.
Perhaps anyone has an idea about what is going wrong in this case, For
clarity I paste the parameters used for searching:


<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">41</int>
-
<lst name="params">
<str name="mm">
        2<-1 5<-2 6<90%
    </str>
<str name="facet">on</str>
<str name="facet.mincount">1</str>
<str name="tie">0.01</str>
<str name="qf">
    category_search
     </str>
<str name="f.category.hl.fragsize">0</str>
<str name="hl.simple.pre"><em></str>
<str name="q.alt">
    *:*
     </str>
<str name="hl.fl">category</str>
<str name="hl">true</str>
<str name="defType">dismax</str>
<str name="echoParams">all</str>
<str name="fl">
        *,score
     </str>
<str name="hl.useFastVectorHighlighter">true</str>
<str name="hl.snippets">1</str>
<str name="hl.simple.post"></em></str>
<str name="hl.usePhraseHighlighter">true</str>
<str name="fq">
    shop_name:colorbob.dk
     </str>
-
<arr name="facet.pivot">
<str>root_category_name,parent_category_name,category</str>
<str>root_category_id,parent_category_id,category_id</str>
</arr>
<str name="ps">100</str>
-
<arr name="facet.pivot">
<str>root_category_name,parent_category_name,category</str>
<str>root_category_id,parent_category_id,category_id</str>
</arr>
<str name="q">OKI</str>
<str name="rows">100</str>
</lst>
</lst>

I see no pattern in what queries is returning the pivot fields and which
ones are not


The field searched in is defined as:

<field name="category_search" type="edgytext" indexed="true" stored="false"
required="false" termVectors="on" termPositions="on" termOffsets="on" />

And the edgytext type is defined as
    <fieldType name="edgytext" class="solr.TextField"
positionIncrementGap="100">
         <analyzer type="index">
           <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.WordDelimiterFilterFactory"
stemEnglishPossessive="0" splitOnNumerics="0" preserveOriginal="1"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="1" />
        <filter class="solr.LowerCaseFilterFactory"/>
           <filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="25" />
         </analyzer>
         <analyzer type="query">
           <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.WordDelimiterFilterFactory"
stemEnglishPossessive="0" splitOnNumerics="0" preserveOriginal="1"
generateWordParts="1" generateNumberParts="1" catenateWords="0"
catenateNumbers="0" catenateAll="0" />
        <filter class="solr.LowerCaseFilterFactory"/>
         </analyzer>
    </fieldType>

I am using apache-solr-4.0-2010-11-26_08-36-06 release

Thanks in advance,
