    <p>I use solr 3.6 and I would like to use collations from suggester as a autocomplete solution for multi term searches. Unfortunately the Suggester returns only one collation for a multi term search, even if a lot of suggestions for each single term exists. Depending on my test searches and the underlying indexed data I'm sure that more collations must exist.</p> <p>Is something wrong with my Suggester configuration?</p> <pre><code> &lt;!--configuration --&gt; &lt;searchComponent class="solr.SpellCheckComponent" name="suggest"&gt; &lt;lst name="spellchecker"&gt; &lt;str name="name"&gt;suggest&lt;/str&gt; &lt;str name="classname"&gt;org.apache.solr.spelling.suggest.Suggester&lt;/str&gt; &lt;str name="lookupImpl"&gt;org.apache.solr.spelling.suggest.fst.WFSTLookupFactory&lt;/str&gt; &lt;str name="field"&gt;text&lt;/str&gt; &lt;!-- the indexed field to derive suggestions from --&gt; &lt;!--&lt;float name="threshold"&gt;0.0005&lt;/float&gt; disabled for test--&gt; &lt;str name="buildOnCommit"&gt;true&lt;/str&gt; &lt;/lst&gt; &lt;/searchComponent&gt; &lt;requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest"&gt; &lt;lst name="defaults"&gt; &lt;str name="spellcheck"&gt;true&lt;/str&gt; &lt;str name="spellcheck.dictionary"&gt;suggest&lt;/str&gt; &lt;str name="spellcheck.onlyMorePopular"&gt;true&lt;/str&gt; &lt;str name="spellcheck.count"&gt;200&lt;/str&gt; &lt;str name="spellcheck.collate"&gt;true&lt;/str&gt; &lt;str name="spellcheck.maxCollations"&gt;10&lt;/str&gt; &lt;/lst&gt; &lt;arr name="components"&gt; &lt;str&gt;suggest&lt;/str&gt; &lt;/arr&gt; &lt;/requestHandler&gt; </code></pre> <p>Example response for q=bio+ber :</p> <pre><code>&lt;response&gt; &lt;lst name="responseHeader"&gt; &lt;int name="status"&gt;0&lt;/int&gt; &lt;int name="QTime"&gt;4&lt;/int&gt; &lt;/lst&gt; &lt;lst name="spellcheck"&gt; &lt;lst name="suggestions"&gt; &lt;lst name="bio"&gt; &lt;int name="numFound"&gt;27&lt;/int&gt; &lt;int name="startOffset"&gt;0&lt;/int&gt; &lt;int name="endOffset"&gt;3&lt;/int&gt; &lt;arr name="suggestion"&gt; &lt;str&gt;bio&lt;/str&gt; &lt;str&gt;bio-estetica&lt;/str&gt; &lt;str&gt;bio-kosmetik&lt;/str&gt; ... &lt;/arr&gt; &lt;/lst&gt; &lt;lst name="ber"&gt; &lt;int name="numFound"&gt;81&lt;/int&gt; &lt;int name="startOffset"&gt;4&lt;/int&gt; &lt;int name="endOffset"&gt;7&lt;/int&gt; &lt;arr name="suggestion"&gt; &lt;str&gt;beratung&lt;/str&gt; &lt;str&gt;bern&lt;/str&gt; ... &lt;/arr&gt; &lt;/lst&gt; &lt;str name="collation"&gt;bio beratung&lt;/str&gt; &lt;/lst&gt; &lt;/lst&gt; &lt;/response&gt; </code></pre>

    1. CORan into this problem myself, just using the basic Solr toy app (start.jar). I tried every conceivable combination of spellcheck parameters, including spellcheck.maxCollations, but can't seem to get more than one collation. Any insights would be appreciated.

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.
