Modifie our Kodi Addon Need Expert

I have an add-on and we want to insert a search engine into it, so when someone searches for a football match, writes the name of the team and automatically shows you all the results on Kodi. I'll give another example: in the add-on there's a movie; I would like that looking for the film comes in the integrated search engine, and so for every content. Contact me only if you understand the request and above all if you know Kodi.
