Search for content containing HTML code (URL's)

A previous content editor, has build included HTML code inside contact areas, mainly “a ref” to link out to url’s on other websites and our own website. We have moved the content of most of these to new URL’s.


The search on the Contentful interface excludes HTML searching, ie search for “.aspx” and nothing is returned, even though content exists within an “a ref”.

Does anyone know of a way for search the Contact for HTML code?
