Question

我正在云模式下配置Solr，并且想要配置自定义查询解析器。配置它我使用PowerShell脚本如下。

# Variables ###########
$hostName = 'localhost'
$port = 8983
$numberOfShards = 1
$replicationFactor = 1

# These should be picked from an external file
$collections = 'Collection1', 'Collection2', 'Collection3', 'Collection4', 'Collection5', 'Collection6', 'Collection7', 'Collection8', 'Collection9';
#######################

# Following 3 commands needs file system access and can be extracted out of this script in case we want to use already hosted Solr instance on cloud
# Start Solr in Cloud Mode
'####### Starting Solr #######';
..\bin\solr start -c -h $hostName -p $port "-Denable.runtime.lib=true"

# Upload configuration to ZooKeeper
# We need to upload multiple copies of the configuration to the ZooKeeper one for each collection, so each collection can have it's different schema
$zooKeeperPort = $port + 1000;
foreach ($c in $collections) {
    $configName = $c + 'SearchConfig';
    '####### Uploading Config to ZooKeeper for collection {0} #######' -f $c;
    $configPath = './xuber_basic_config/conf/';
    ..\server\scripts\cloud-scripts\zkcli.bat -zkhost localhost:$zooKeeperPort -cmd upconfig -confdir $configPath -confname $configName;
}

$urlPrefix = 'http://' + $hostName + ':' + $port + '/solr';

function PostToSolr
{
   'HTTP POST: {0}' -f $args[0];
   Invoke-WebRequest -uri $args[0] -Method POST -ContentType "application/json" -Body $args[1];
}

function GetToSolr
{
    'HTTP GET: {0}' -f $args[0];
    Invoke-WebRequest -uri $args[0] -Method GET -ContentType "application/json";
}

function PostSchema
{
    $schemaFileName = $args[0];
    $url = $args[1];
    $jsonToPost = Get-Content ./$schemaFileName;
    PostToSolr $url $jsonToPost;
}

# Get a list of collections already present in Solr
$readCollectionUrl = $urlPrefix + '/admin/collections?action=LIST&wt=json';
$alreadyExistingCollections = ((GetToSolr $readCollectionUrl).Content | ConvertFrom-Json).collections;

# Create .system collection
$systemCollectionName = '.system';
If ($alreadyExistingCollections -contains $systemCollectionName) {
    $deleteCollectionUrl = $urlPrefix + '/admin/collections?action=DELETE&name={0}' -f $systemCollectionName;
    GetToSolr $deleteCollectionUrl;
}

$addSystemCollectionPath =  $urlPrefix + '/admin/collections?action=CREATE&name=' + $systemCollectionName;
GetToSolr $addSystemCollectionPath;

$dataSecurityPlugin = 'customQueryPlugin';
$addBlobPath = $urlPrefix + '/'+ $systemCollectionName + '/blob/' + $dataSecurityPlugin;
'HTTP POST: {0}' -f $addBlobPath;
Invoke-WebRequest -uri $addBlobPath -Method Post -InFile .\customQueryPlugin.jar -ContentType application/octet-stream;

$createCollectionPrefix = $urlPrefix + '/admin/collections?action=CREATE&name={0}&numShards={1}&replicationFactor={2}&collection.configName={3}';
$schemaApiUrlPrefix = $urlPrefix + '/{0}/schema';

# Create Solr Collections
foreach ($c in $collections) {
    # Check to see if the collection already exists, if yes, delete it.
    If ($alreadyExistingCollections -contains $c) {
        '####### Collection {0} already present hence deleting it #######' -f $c
        $deleteCollectionUrl = $urlPrefix + '/admin/collections?action=DELETE&name={0}' -f $c;
        GetToSolr $deleteCollectionUrl;
    }

    '####### Creating collection {0} #######' -f $c;
    $configName = $c + 'SearchConfig';
    $tempPath = $createCollectionPrefix -f $c,$numberOfShards,$replicationFactor,$configName;
    GetToSolr $tempPath;

    # Add data security plugin to runtime
    $addToRuntimePath = $urlPrefix + '/'+ $c + '/config';
    $runtimeJsonData = @{"add-runtimelib" = @{name = "customQueryPlugin"; version = 1}} | ConvertTo-Json;
    $runtimeJsonData;
    PostToSolr $addToRuntimePath $runtimeJsonData;

    $schemaAddUrl = $schemaApiUrlPrefix -f $c;
    # Push the common Schema
    '####### Adding common schema for collection {0} #######' -f $c;
    $schemaFileName = 'Common_Schema.json';
    PostSchema $schemaFileName $schemaAddUrl;

    # Push the Schema specific to the collection
    '####### Adding specific schema for collection {0} #######' -f $c;
    $schemaFileName = $c + '_Schema.json';
    PostSchema $schemaFileName $schemaAddUrl;

    # Register QueryParser
    $addQueryParserPath = $addToRuntimePath;
    $addQueryParserData = @{"create-queryparser" = @{name = "acl"; runtimeLib = $true; class = "customQueryPlugin.customSearchQueryParser"}} | ConvertTo-Json;
    PostToSolr $addQueryParserPath $addQueryParserData;
}

我正在使用edismax，并且能够在没有过滤器查询的情况下搜索我的数据但是使用过滤器查询它没有提供任何数据，你能判断我是否遗漏了什么吗？

我认为线索在你脚本的最后几行：

double heightpixel = metrics.heightPixels;
double widthpixel = metrics.widthPixels;

您确定$addQueryParserData = @{"create-queryparser" = @{name = "acl"; runtimeLib = $true; class = "customQueryPlugin.customSearchQueryParser"}} | ConvertTo-Json;变量：$true？我打赌它应该是runtimeLib = $true。

还值得注意的是Query Parser类的名称：runtimeLib = true。请确保您的class = "customQueryPlugin.customSearchQueryParser"确实将其作为完全限定名称。

如何配置Solr自定义查询解析器？
