使用 Solarium php 建议查询中的 HTTP 错误问题

Question

I'm implement suggest query in php codeigiter using solarium. But while connect to the createSuggester query. It shows following error line.

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:

My sample code is here,

$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();

I'm try to find solution in many resources. But the solution is not there. Plese explain me what/why this issue is happened?

Answer 1

you can set the default dictionary in "solrconfig.xml" like this:

<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>

and remove this line from your code:

$query->setDictionary('suggester');

Answer 2

not 'suggester' at $query->setDictionary('suggester') ,please use the name of the suggester like $query->setDictionary('mySuggester')
