How can I use query.fullText()?

Moralis General
#23

It returns this value.

tokenURIData_text

Should I need to use this return value like this?

query.fullText('tokenURIData_text', 'xxx')
#24

How can I list indexes?
Could you tell me how to list indexes?

#25

I listed indexes.

[
  { v: 2, key: { _id: 1 }, name: '_id_' },
  {
    v: 2,
    key: { _fts: 'text', _ftsx: 1 },
    name: 'tokenURIData_text',
    weights: { tokenURIData: 1 },
    default_language: 'english',
    language_override: 'language',
    textIndexVersion: 3
  }
]
#26

Do you still get an error?

#27

Yeah, it still occurs exception.

{"ok":0,"code":27,"codeName":"IndexNotFound","name":"MongoError"}
#28

Did you try the exact syntax used here for the query?

#29

This is my creating index code.

await client.db('admin').command({ ping: 1 });
console.log('Connected successfully to server');

const database = client.db("parse")
const collection = database.collection("TblColllection")

const res = await collection.createIndex({ tokenURIData: "text" })

So after this code, I listed the indexes and result is like below.

[
  { v: 2, key: { _id: 1 }, name: '_id_' },
  {
    v: 2,
    key: { _fts: 'text', _ftsx: 1 },
    name: 'tokenURIData_text',
    weights: { tokenURIData: 1 },
    default_language: 'english',
    language_override: 'language',
    textIndexVersion: 3
  }
]

And I used query.fullText method on cloud function as below.

query.fullText('tokenURIData', request.params.keyword);
#30

The original code was also doing a query after creating the index

#31

Yeah, right. But the code was on client side.
But I need to implement this feature on cloud functions.

#32

yes, just wanted to know if it works that code in client side that was used there

#33

I added this code on client side and it is also not working.

const datas = await collection.aggregate([{ $match: { $text: { $search: "test" } } }]).toArray();
console.log(datas);

And there’s a record which tokenURIData contains ‘test’, but it returns empty array.

#34

original code

await client.connect()

const database = client.db("parse")
const collection = database.collection("itemCreatedData")

await collection.createIndex({ title: "text" })

const datas = await collection.aggregate([{ $match: { $text: { $search: "queen" } } }]).toArray()

new code:

await client.db('admin').command({ ping: 1 });
console.log('Connected successfully to server');

const database = client.db("parse")
const collection = database.collection("TblColllection")

const res = await collection.createIndex({ tokenURIData: "text" })

const datas = await collection.aggregate([{ $match: { $text: { $search: "test" } } }]).toArray();
console.log(datas);

seems similar

maybe you can also try this: const datas = await collection.aggregate([{ $match: { $tokenURIData_text: { $search: "test" } } }]).toArray();
I think that you already tried it.

It may be easier to use a regexp

#35

Yeah, I tried and it works the same. :sob:

#36

regexp part doesn’t work either?

#37

When I use regexp on normal javascript, we don’t use quote like below.
regexp = /test/g;

But when I use this format on cloud function, it returns an error and requires regexp as string.
So I used ‘/test/g’, but in my opinion, in this case, it is searching ‘/test/g’ string not regexp string.

#38

And I tried with this code and in this case it occurs exception but exception is an empty object.

            pipelin.push({
                match: {
                    tokenURIData: { $regex: `/${request.params.keyword}/g` },
                },
            })
#39

regexp should work without issues, try with simpler queries maybe, hardcoded values

#40

I tried in various solutions with regexp.
Could you send me the sample code which check if column contains the substring?
Thanks.

#41

this is the other solution that could work for you:

#42

Yeah, it works.
Thanks for your continous support!!! :+1:
