How to filter by multiple values using .includes?

Question

I'm filtering some records according to the their string content using the .includes function.

Here a snap of my code


 var oav = ["baluardo"]

...

  if (((item.metadata["pico:record"]["dc:description"]["_"]).length >= 10 &&
                    (item.metadata["pico:record"]["dc:description"]["_"]).length <= 400) && (item.metadata["pico:record"]["dc:description"]["_"])
                    .includes(oav) 
                    )

... do something ...

Using one term the .includes function works properly, adding one more term like this


var oav = ["baluardo", "Fortezza"]

doesn't work and I'm having an empty array.

Suggestions?

So you want to check if your metadata includes atleast one of those strings in oav or you want to check if your metadata includes all of those strings in oav? — AndrewL64

Make your life easier with an intermediate variable: const meta = item.metadata["pico:record"]["dc:description"]["_"] — jarmod

Does this answer your question? multiple conditions for JavaScript .includes() method — Gerard

You can use .every() to check if every element in oav is in the metadata.

var oav = ["baluardo", "Fortezza"]

//not actual metadata
var meta = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "baluardo", "Fortezza"];

if (meta.length >= 10 && meta.length <= 400 && oav.every(o => meta.includes(o))) {
  console.log("meta includes baluardo and Fortezza");
}

Use two some() functions to compare the search terms to the description value:

const result = searchTerms.some(word => inputArr.some(el => el.desc.includes(word)))

function findSearchTerms(inputArr, searchTerms){
    if (inputArr.length >= 0 && inputArr.length <= 10 && searchTerms.some(word => inputArr.some(el => el.desc.includes(word)))){
        console.log("one or more of these elements includes a search term")                   
    }else{
        console.log("none of these elements includes a search term")                   
    }
}


const terms = ["baluardo", "Fortezza"]
let arr = [{desc:"baluardo etc."},{desc:"etc. Fortezza"},{desc:"Other desc"}]

findSearchTerms(arr,terms)

arr = [{desc:"etc."},{desc:"etc."},{desc:"Other desc"}]

findSearchTerms(arr,terms)
