How to look for strings in array using regex with MongoDB.? - node.js

Question

I have several objects like this:
"status": "published",
"term_id": [
"anime",
"sci-fi",
"etc"
],
"captionCert": "1",
I know that in order to look within a single field, I would create something like this:
if (keyword) {
query.status = { $regex: keyword, $options: 'i' };
}
Where keyword comes from the front end and can be whatever the user types; then I proceed to look into the field status and then I just retrieve it by passing it into my model query:
Video.find(query)
Now hte problem is that I need to know how to exactly do this but inside the term_id array?
Any idea? Thanks.
UPDATE: I'm trying to implement it into this function:
exports.searchVideos = asyncHandler(async (req, res, next) => {
const query = {};
const { keyword } = req.query;
if (keyword) {
query.title = { $regex: keyword, $options: 'i' };
} else {
query.text = { $regex: keyword, $options: 'i' };
}
if (keyword) {
query.term_id = { term_id: { $regex: keyword, $options: 'i' } };
};
const video = await Video.find(query).select(
'title text thumbnail video_url term_id'
);
console.log(query);
res.status(200).json({ success: true, data: video });
});

Solution after finding out about $or operator. This solved my problems!:
exports.searchVideos = asyncHandler(async (req, res, next) => {
let query = {};
const { keyword } = req.query;
query = {
$or: [
{ title: { $regex: keyword, $options: 'i' } },
{ text: { $regex: keyword, $options: 'i' } },
{ term_id: { $regex: keyword, $options: 'i' }}
]
};
const video = await Video.find(query).select(
'title text thumbnail video_url term_id'
);
res.status(200).json({ success: true, data: video });
});
