monogdb full text search, ignore characters - regex

Question

Im implementing a mongodb search.
The search performs a find on field values:
[{
value: "my.string.here"
}, {
value: "my other here"
}{
...
}]
When i enter "my" both entries are found. What have my query to look like to ignore the dots on the first entry? So when i enter "my string" the first element gets returned?
Actually it works only when i enter "my.string" which is not nice.
let limit = Number(req.query.limit || 100);
let skip = Number(req.query.skip || 0);
collection.find({
$or: [{
value: new RegExp(req.body.search, "gi")
}, {
tags: {
$in: req.body.search.split(",").map((val) => {
return new RegExp(val, "gi")
})
}
}]
}).skip(skip).limit(limit).toArray((err, result) => {
if (err) {
res.status(500).json(err);
} else {
res.status(200).json(result);
}
});
EDIT:
A solution could look like this:
let query = {
$or: [{
name: new RegExp(req.body.search, "gi")
}, {
tags: {
$in: req.body.search.split(",").map((val) => {
return new RegExp(val, "gi")
})
}
}, {
name: new RegExp(req.body.search.split(' ').join('.'), "gi")
}, {
name: new RegExp(req.body.search.split(' ').join('_'), "gi")
}, {
name: new RegExp(req.body.search.split(' ').join('-'), "gi")
}]
};
But i find it ugly and not elegant. Is there a better way to do this ?
