Hi Eric and everybody else!
Thanks for trying to help. Here is the example:
.../terms?terms.regex.flag=case_insensitive&terms.fl=suggest&terms=true&terms.limit=20&terms.sort=index&terms.prefix=1n1187
returns
<int name="1n1187">1</int>
<int name="1n1187a">1</int>
<int name="1n1187r">1</int>
<int name="1n1187ra">1</int>
This list contains 3 complete part numbers but the third item (1n1187r) is not
a complete part number. Is there a way to make terms tell if a term represents
a complete value?
(My guess is that this gets lost after ngram but I'm still hoping something can
be done.)
More config details:
<field name="suggest" type="text_parts" indexed="true" stored="true"
required="false" multiValued="true"/>
and
<fieldType name="text_parts" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="20" side="front"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Thanks,
Alexander

Not quite sure what you mean here, a couple of examples would help.
But since the term is using keyword tokenizer, then each thing you get back is
a complete term, by definition. So I'm not quite sure what you're asking
here.....
