    <p>Im currently working on a solr based search application.</p> <p>I have two multivalued fields for example: The data is read out of a database.</p> <pre><code>&lt;int name="id"&gt;1&lt;/int&gt; &lt;arr name="type"&gt; &lt;str&gt;Marke&lt;/str&gt; &lt;str&gt;Modell&lt;/str&gt; &lt;str&gt;Fahrzeugtyp&lt;/str&gt; &lt;str&gt;engine&lt;/str&gt; &lt;/arr&gt; &lt;arr name="value"&gt; &lt;str&gt;Volkswagen&lt;/str&gt; &lt;str&gt;Golf&lt;/str&gt; &lt;str&gt;Golf TDI&lt;/str&gt; &lt;str&gt;V-Engine&lt;/str&gt; </code></pre> <p>In my current solr configuration there is no relationship between these two multivalued fields. So that i can say "Marke = Volkswagen". </p> <p>Besides there must be a relationship between Volkswagen and Golf. So I have to structure a taxonomy out of the two multivalued fields and of the values in the multivalued field itself.</p> <p>I tried to build a typeAhead. In my current config when i search for Volkswagen - the possible suggestions contain audi and engine2 which does not refer to a Volkswagen model. solr url:<br /><br /> <a href="http://xyz:8983/solr/suggest?&amp;wt=json&amp;facet=true&amp;q=" rel="nofollow noreferrer">http://xyz:8983/solr/suggest?&amp;wt=json&amp;facet=true&amp;q=</a>*&amp;facet.field=value&amp;facet.prefix=Volkswagen <br /><br /> I think <a href="https://stackoverflow.com/questions/9521304/solr-faceting-on-multiple-concatenated-fields">Solr Faceting on Multiple Concatenated Fields</a> has something to do with it, but I can't adjust it on my problem. </p> <p>Thanks in reply</p> <hr> <p>Maybe I can use the TemplateTransformer to combine value and type?</p> <hr> <p>With TemplateTransformer I get a result: Marke | Volkswagen</p> <p>In my data-import.xml (DIH)</p> <pre><code>&lt;entity&gt; name="tablename" transformer="TemplateTransformer"&gt; &lt;field column="test" template="${tablename.TYPE} | tablename.VALUE}"/&gt; ... &lt;/entity&gt; </code></pre> <hr>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
