Fetching documents based of multiply values

Question

My documents have categories. it can be both a single or many ("category 1, category 2,..)

I have been trying to use regular expressions in order to fetch using the following code, so far with no luck:

  const categoriesStr = category.replace(",", "|");
  params.category = `\\${categoriesStr}\\`;

Answer 1

I assume you're trying to do something like this:

const category = "category 1, category 2"
const categoriesStr = category.replace(/,\s*/g, "|"); // Replace all commas with "|"
const params = {};
params.category = new RegExp(`^(${categoriesStr})$`, "i"); // Create a regular expression

console.log(params.category);
