使用Solarium php进行建议查询时出现HTTP错误问题

Question

我正在用日光实现php codeigiter的建议查询。但是当连接到createSuggester查询时。它显示以下错误行。

An uncaught Exception was encountered
Type: Solarium\Exception\HttpException

Message: Solr HTTP error: OK (404)
HTTP ERROR 404
Problem accessing /solr/../suggest. Reason:

    Not Found
Filename: C:\wamp\www\solariumphp\vendor\solarium\solarium\src\Core\Query\Result\Result.php

Line Number: 59

Backtrace:

File: C:\wamp\www\solariumphp\vendor\solarium\solarium\src\Core\Client\Client.php

Line: 30
Function: suggester

File: C:\wamp\www\solariumphp\index.php
Line: 315
Function: require_once

我的示例代码在这里，

$query = $this->client->createSuggester();
$query->setQuery('ap ip v'); //multiple terms
$query->setDictionary('suggester');
// $query->setOnlyMorePopular(true);
$query->setCount(10);
// $query->setCollate(true);

// this executes the query and returns the result
$resultset = $this->client->suggester($query);

echo '<b>Query:</b> '.$query->getQuery().'<hr/>';

// display results for each term
foreach ($resultset as $term => $termResult) {
    echo '<h3>' . $term . '</h3>';
    echo 'NumFound: '.$termResult->getNumFound().'<br/>';
    echo 'StartOffset: '.$termResult->getStartOffset().'<br/>';
    echo 'EndOffset: '.$termResult->getEndOffset().'<br/>';
    echo 'Suggestions:<br/>';
    foreach ($termResult as $result) {
        echo '- '.$result.'<br/>';
    }

    echo '<hr/>';
}

// display collation
echo 'Collation: '.$resultset->getCollation();

我试图在许多资源中找到解决方案。但解决方案并不在那里。请向我解释发生此问题的原因？

Answer 1

您可以在"solrconfig.xml“中设置默认字典，如下所示：

<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
    <str name="name">mySuggester</str>
    <str name="lookupImpl">FreeTextLookupFactory</str>
    <str name="dictionaryImpl">DocumentDictionaryFactory</str>
    <str name="field">content</str>
    <str name="suggestFreeTextAnalyzerFieldType">suggestTypeLc</str>
    <str name="buildOnStartup">true</str>
    <str name="buildOnCommit">false</str>
</lst>
</searchComponent>

<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>

并从您的代码中删除这一行：

$query->setDictionary('suggester');

Answer 2

不是$query->setDictionary('suggester')上的'suggester'，请使用推荐人的名字，如$query->setDictionary('mySuggester')
