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"/>
...
<field name="text_suggest" type="textSuggest" indexed="true"
stored="true" multiValued="true" />
...
<copyField source="roadName" dest="text_suggest" />
<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.

First off, kudos for providing the details, that really helps!
The root of your problem is that your suggest field has stored="false".
DocumentDictionaryFactory reads through all the
docs in your corpus, extracts the stored data and puts it in the FST. Since
you don't have any stored data your FST is...er...minimal.
I'd also add
<str name="storeDir">suggester_fuzzy_dir</str>
to the searchComponent. You'll find the FST on disk in that directory where it
can be read next time Solr starts up. It is also helpful for figuring out
whether there are suggestions to be had.
And a minor nit, you probably don't want to specify suggest.dictionary
in your query,
that's already specified in your config.
And it looks like you're alive to the fact that with that setup
capitalization matters
as does the fact that these suggestions be matched from the beginning of the
field...
Best,
Erick

Hi there,
I want to use the Solr suggester component for city names. I have the
following settings:
schema.xml
Field definition
<fieldType class="solr.TextField" name="textSuggest" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
The field i want to apply the suggester on
<field name="city" type="string" indexed="true" stored="false"/>
The copy field
<copyField source="city" dest="citySuggest"/>
The field
<field name="citySuggest" type="textSuggest" stored="false" indexed="true" />
solr-config.xml
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="suggest">true</str>
<str name="suggest.count">10</str>
<str name="suggest.dictionary">mySuggester</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">FuzzyLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">citySuggest</str>
<str name="suggestAnalyzerFieldType">string</str>
</lst>
</searchComponent>
Then i run
http://localhost:8983/solr/company/suggest?suggest=true&suggest.dictionary=mySuggester&wt=json&suggest.q=Ath&suggest.build=true
to build the suggest component
Finally i run
http://localhost:8983/solr/company/suggest?suggest=true&suggest.dictionary=mySuggester&wt=json&suggest.q=Ath
but i get an empty result set
{"responseHeader":{"status":0,"QTime":0},"suggest":{"mySuggester":{"Ath":{"numFound":0,"suggestions":[]}}}}
Are there any obvious mistakes? Any thoughts?
