Undefined factory sphinx

Anyone also face this issue? if then how to resolve it?

Answer 1

I don't know how sphinx works, but your search engine requires a factory attached to the Magento\CatalogSearch\Model\Search\ItemCollectionProvider class.
You can do this via di.xml of one of your modules (probably the sphinx module itself)

<type name="Magento\CatalogSearch\Model\Search\ItemCollectionProvider">
    <arguments>
        <argument name="factories" xsi:type="array">
            <item name="sphinx" xsi:type="object">class name or virtual type name here</item>
        </argument>
    </arguments>
</type>

Here is an example on how it works for elasticsearch6. vendor/magento/module-elasticsearch-6/etc/di.xml

<type name="Magento\CatalogSearch\Model\Search\ItemCollectionProvider">
    <arguments>
        <argument name="factories" xsi:type="array">
            <item name="elasticsearch6" xsi:type="object">elasticsearchAdvancedCollectionFactory</item>
        </argument>
    </arguments>
</type>

where elasticsearchAdvancedCollectionFactory is a virtual type defined in vendor/magento/module-elasticsearch/etc/di.xml

 <virtualType name="elasticsearchAdvancedCollectionFactory" type="Magento\CatalogSearch\Model\ResourceModel\Advanced\CollectionFactory">
    <arguments>
        <argument name="instanceName" xsi:type="string">elasticsearchAdvancedCollection</argument>
    </arguments>
</virtualType>

where elasticsearchAdvancedCollection is another virtual type. you can search for it further in di.xml files.
