Lua function for string.match multiple words and numbers

Question

If I have a search box and want to find if a string contains certain words (not case sensitive) and/or numbers.

search = "Brown lazy 46"
textline = "The quick brown fox jumped over 46 lazy dogs"
if string.match(textline, search) then
  result = textline
end

just like a web search.

What have you tied to do to solve this problem? first obvious solution is loop over your search terms and check they are in the text provided. — Nifim, Dec 17 '21 at 19:31

search = "Brown lazy 46"
textline = "The quick brown fox jumped over 46 lazy dogs"

for item in string.gmatch(search, "%S+") do 
if string.find(textline, string.lower(item)) then
   result = textline
    end
end

You break up the word values you are looking for and convert them into an array. Then you should loop that array and check if your main variable is in it.

If I understood correctly what you want to do this should solve your problem.

I just had to change it all to lowercase it to work "if string.find(string.lower(textline), string.lower(item)) then" – LuaStart Dec 18 '21 at 21:13
