Disable creation of certain Mongo indexes?

[clarkritchie]

Hi and thanks for this package!

It looks like this package automatically creates a bunch of Mongo indexes when the app starts up.

Is there any way to tell it to not create a specific index? I'm occasionally getting a MongoError: E11000 duplicate key error on a field that I don't ever need to search on.

I noticed I can:

• db.users.getIndexes() -- see the problem index
• db.users.dropIndex('services.phone.verify.code_1'); -- index is gone
• restart app, index comes back
• meteor remove easy:search -- for testing
• restart app, no indexes
• meteor add easy:search
• restart app -- see the problem index

Yes that might be the case, are you using the MongoTextIndex package? It creates a text index for the fields that you want to search on. You don't need to specify those fields as you could add a custom selector method to add other functionality in there.

Please show me an example of your configuration.

No, I'm not using MongoTextIndex. As above, when I add this package, I see the index in the db. When I remove this package, the index goes away.

You don't have any configuration at all? Simply adding the package creates indexes? Please show me the EasySearch related code from your app.

Pretty much this:

// setup specific server-side EasySearch search indexes
if (Meteor.isServer) {
    // good configuration examples:  https://github.com/matteodem/easy-search-leaderboard/blob/master/leaderboard.js
    VouchersIndex = new EasySearch.Index({
        collection: Vouchers,
        defaultSearchOptions: {
            limit: 10000 // total WAG
        },
        fields: ['code', 'identifier'],
        engine: new EasySearch.MongoDB()
    });

    OrdersIndex = new EasySearch.Index({
        collection: Orders,
        defaultSearchOptions: {
            limit: 10000 // total WAG
        },
        fields: ['userId'],
        engine: new EasySearch.MongoDB()
    });

    PaymentsIndex = new EasySearch.Index({
        collection: Payments,
        defaultSearchOptions: {
            limit: 10000 // total WAG
        },
        fields: ['senderPhone', 'transactionReference', 'firstName', 'lastName'],
        engine: new EasySearch.MongoDB()
    });

    UsersIndex = new EasySearch.Index({
        collection: Meteor.users,
        defaultSearchOptions: {
            limit: 10000 // total WAG
        },
        fields: ['profile.name', 'phone.number'],
        engine: new EasySearch.MongoDB()
    });
}

I'll lower the priority of this as the only place in the core code that touches / creates an index is when the MongoTextIndex engine is used. See here
