  Since you only have raw HTML in the redactor field and there is no real relationship between the asset in the craft and the img url, the only way to do this is to [parse your readctor field](https://www.php.net/manual/en/domdocument.loadhtmlfile.php) (or maybe even [this](https://simplehtmldom.sourceforge.io/docs/1.9/index.html)?), check the img tags, take the "src" part and check in the assets table (the last part of the path in the *src*).
  
  ```
  ...<img src="http://mysite.com/assetFolder/subfolder/**file_name.jpg**">
  
  ```
  
  And then find it like this:
  
  ```
  \craft\elements\Asset::find()->filename($parsedImgSrcValue);
  
  ```

  If your end goal is simply to have a dynamic index/list of all entries where that field contains that string, you can use the new filtering options in the entries index list here:
