Prioritize keywords found in title in sql search

Navigation

Hello, I have a 'videos' table with 3 fields 'name', 'description' and 'categories'. When doing a search I want to appear at the top videos that in the 'name' have more of these keywords, for example if I search "beautiful house" a video with name 'CASA in Alagoas BONITA' has to stay more on top than a video with name "sao paulo CASA" and description "look how beautiful it is" (because I do the research looking for the key words in name and description).

Does anyone have an idea how to do this?

This subject may be much more complex than it appears to be. The relevant search, so to speak.

But, answering your question more directly, I would suggest using the UNION clause. 

SELECT * (<condicoes com alta prioridade>)
UNION
SELECT * (<condicoes com um pouco menos de prioridades>)
UNION
SELECT * (<condicoes com menos de prioridades ainda>)

Or, another suggestion is to use a ranking variable

  

SELECT t. *, [ranking expression] AS ranking FROM () AS t ORDER BY   ranking DESC
