Solr：一词查询与三词索引值不匹配

Question

One of my documents has a title attribute with the value Poésie pour pouvoir . When I query q=title:poesie , no results are found. q=title:poesie pour finds the document, though.

title is of type text . Excerpt from my schema.xml:

<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.ASCIIFoldingFilterFactory" />
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1"
                catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
        <filter class="solr.SnowballPorterFilterFactory" language="German2"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
    </analyzer>
    <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1"
                catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
        <filter class="solr.SnowballPorterFilterFactory" language="German2"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
    </analyzer>
</fieldType>

The second query isn't searching the title field only - it's also searching the default search field. The query is parsed as "title:poesie default_field:pour". The second part is what's generating the hit.

You can use the debugQuery parameter to see how your query is being parsed. Use the analysis page under the Solr admin page to see why the title value doesn't match (input "Poésie pour pouvoir" under "indexed" value and "poesie" under query value).
