Bradley:
You're a bloody genius!
That's exactly what I needed to make it work.
For the sake of the archives, after modifying the solrconfig.xml as
indicated and rebuilding the suggester dictionary, the queries started
to kick back results like crazy.
For what it's worth, I'm running Solr 6.1.0.
Thanks so much.

Scott, I’m fairly new to suggesters having just recently built my first one.
But where my configuration differs from yours is on this line:
<str name="suggestAnalyzerFieldType">string</str>
I used the field type name that I had defined instead like:
<str name="suggestAnalyzerFieldType"> textSuggest </str>
I’m not certain that would help, but I can’t see where your config is much
different form mine elsewhere.
What version of Solr are you running?

I'm having the exact same problem the O.P. describes from his email back
in May, but my configuration dose not have the same defect his had. So I
am at a loss to understand why my suggest queries are returning no results.
Here is my config:
Relevant bits from schema.xml:
--------------------------------------
<field name="roadName" type="string" indexed="true" stored="true"
multiValued="true"/>
<field name="commentaryP" type="text_general" indexed="true"
stored="true" multiValued="true"/>

<copyField source="commentaryP" dest="text_suggest" />

<fieldType class="solr.TextField" name="textSuggest"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Relevant bits from solrconfig.xml:
--------------------------------------
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="suggest.dictionary">mySuggester</str>
<str name="suggest">true</str>
<str name="suggest.count">10</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
...
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">AnalyzingInfixLookupFactory</str>
<str name="indexPath">suggester_infix_dir</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">text_suggest</str>
<str name="suggestAnalyzerFieldType">string</str>
<str name="buildOnStartup">false</str>
<str name="buildOnCommit">false</str>
</lst>
</searchComponent>
I build the dictionary like this:
http://example.com:8983/solr/rrib/suggest?suggest.build=true
and get back this response:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">964</int>
</lst>
<str name="command">build</str>
</response>
I then attempt a query like this:
http://example.com:8983/solr/rrib/suggest?q=re
and get back this response:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">37</int>
</lst>
<lst name="suggest">
<lst name="mySuggester">
<lst name="re">
<int name="numFound">0</int>
<arr name="suggestions"/>
</lst>
</lst>
</lst>
</response>
In Solr's Admin interface, I see the following under OTHER->suggest on
Plugins/Stats page:
class:suggest
description:Suggester component
src:
version:6.1.0
stats:
mySuggester: SolrSuggester [ name=mySuggester,
sourceLocation=null, storeDir=,
lookupImpl=AnalyzingInfixLookupFactory,
dictionaryImpl=DocumentDictionaryFactory, sizeInBytes=6795 ]
totalSizeInBytes: 6795
The value of 6,795 bytes seems pretty small to me for a repository of
403 XML files containing about 1.5 MB of mark-up. Perhaps that is a clue
that the dictionary has not been fully populated, which probably
explains the empty result sets, but I cannot figure out why
Any assistance would be gratefully received.
Thank you.
