autoGeneratePhraseQueries does not work?

[Akihiro Ito]

HI,

I am using Solr 7.7.1 in SolrCloud mode.

I’m getting a document I shouldn’t when searching with a TextField.
It looks like autoGeneratePhaseQuery is not working as it should, 
but I have no idea what is causing it.

The schema definition I use is as follows.

 <fieldType name=“trigram_type” class=“solr.TextField”
positionIncrementGap=“100” autoGeneratePhraseQueries=“true”>
   <analyzer type=“index”>
     <charFilter class=“solr.ICUNormalizer2CharFilterFactory” name=“nfkc”/>
     <charFilter class=“solr.PatternReplaceCharFilterFactory” pattern=“$”
replacement=“**“/>
     <tokenizer class=“solr.NGramTokenizerFactory” maxGramSize=“3"
minGramSize=“3” />
     <filter class=“solr.PatternReplaceFilterFactory”
pattern=“([^\s])\s[^\s]” replacement=“$1  ” replace=“all”/>
     <filter class=“solr.PatternReplaceFilterFactory” pattern=“^\s.*$”
replacement=“” replace=“all”/>
     <filter class=“solr.LengthFilterFactory” min=“3” max=“3"/>
     <filter class=“solr.LowerCaseFilterFactory”/>
     <filter class=“solr.ICUTransformFilterFactory” id=“Hiragana-Katakana”/>
   </analyzer>
   <analyzer type=“query”>
     <charFilter class=“solr.ICUNormalizer2CharFilterFactory” name=“nfkc”/>
     <tokenizer class=“solr.NGramTokenizerFactory” maxGramSize=“3"
minGramSize=“3” />
     <filter class=“solr.LowerCaseFilterFactory”/>
     
     <filter class=“solr.ICUTransformFilterFactory” id=“Hiragana-Katakana”/>
   </analyzer>
 </fieldType>


Following sample document is in Solr.

docs: [
{
 syo_id: “1237”,
 trigram: “aaabbbccc”,
 ＿version＿: 1639992506850476000,
 timestamp: “2019-07-25T01:38:52.894Z”
}
]

If I execute the following query,it will hit the above document

q=trigram:aaaa&fq=syo_id:1237&debugQuery=on


Thanks,
Akihiro.
