magento 2 EE should not save search terms with zero search results

Question

I am using magento 2.1.8 Enterprise edition. I do not want to save search terms which have zero search results. Is there any solution ?

There is no option in configuration to stop saving the search terms with 0 search results. Please help.

Try this.

Create a custom module and create following files.

File: etc/di.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Search\Model\Query">
        <plugin name="save_greater_then_zero_search_results" type="[Vendor]\[Module]\Plugin\Query" />
    </type>
</config>

File: Plugin/Query.php

<?php

namespace [Vendor]\[Module]\Plugin;

class Query
{
    public function aroundSaveIncrementalPopularity($subject, $callable)
    {
        return $subject;
    }

    public function aroundSaveNumResults($subject, $callable, $numResults)
    {
        if($numResults > 0)
        {
            $subject->getResource()->saveIncrementalPopularity($subject);
            $subject->setNumResults($numResults);
            $subject->getResource()->saveNumResults($subject);
        }

        return $subject;
    }
}

Replace [Vendor] and [Module] with your actual vendor and module name. Hope this helps.
