Related to my question from earlier today. This is also a related post on the topic. We've built a Live Search that fetches the top 20 responses from a collection of 250K names, and we want to do data-fetching correctly.
Currently, if I use:
...ANSWER
Answered 2020-Oct-19 at 21:01As you added in your edit - the question comes mostly down to performance. However, consider not just the performance of a single query, but the performance under production load. How many requests / second do you expect do perform this query?
If it's done once every second or even less often, it will be ok for you for now. But what if the data set grows or you start seeing more requests? that's when you'll start running into issues.
From your example it's not clear to me if a case insensitive "starts_with" search is all that you need. If that's the case, then you can actually use the index for it:
- store the search string additionally in a to_lower or to_upper form
- change your regex to be
^lower cased search string
now your search string is case insensitive and can use an index (it's equivalent to like 'string%'
)
However, keep in mind that using to_lower or to_upper can mess with your text (ToUpperInvariant() – is MSDN wrong on its recommendation?) - and of course if you still need a full text search, this won't work in that case you can
- live with the performance restrictions mentioned above
- live with the feature restrictions of the normal full text search query
- build a custom trigram index (or further research to improve text search in postgres)
- look for alternatives. If you need full text search, maybe a special build DB like ElasticSearch is a better fit for your use case

EDIT: I can use the POJO example with the suggested post to output a list of users in the console, but no Object id
as shown below. Is that the problem causing output not showing to the JSP

QUESTION
Learning the basics of MongoDB, I read that MongoDB is vulnerable to injection attacks out-of-the-box. In node, this can be prevented using the help of the module mongo-sanitize. So far, so good. Now let's add Mongoose to the equation.
If we are using Mongoose
- Do we still need to sanitize MongoDB inputs? Should we still use mongo-sanitize along with Mongoose?
- Does Mongoose offer any explicit injection protection at all, or does the protection come from enforcing types in schemas and models?
I remember reading that Mongoose can prevent injections to some extent, but I don't know the specifics, or if it is redundant to sanitize against Mongoose.
...ANSWER
Answered 2020-Sep-11 at 00:19Like the article mentioned the problem arises when the users doesn't send a string like
'bergur' and 'myawesomepassword' but instead sends {"$ne": null}
for usernames and passwords.
If you create a schema and define username and password as strings, then Mongoose will convert it to string and you avoid the problem.
Regarding the where injection, mongo-sanitize wouldn't help you there. The solution is simply not to ever use the $where operator
So to simply answer your question:
- No you don't need to use mongo-sanitize
- No explicit injection protection, the protection comes from schemas and models.

I've provided a sample project to elucidate this problem: https://github.com/nmarquesantos/spring-mongodb-reactive-indexes
According to the spring mongo db documentation (https://docs.spring.io/spring-data/mongodb/docs/current/reference/html/#mapping-usage):
the @Indexed annotation tells the mapping framework to call createIndex(…) on that property of your document, making searches faster. Automatic index creation is only done for types annotated with @Document.
In my Player class, we can observe the both the @Document and @Indexed annotation:

Answered 2020-Jun-05 at 14:02The Spring Data MongoDB version come with Spring Boot 2.3.0.RELEASE is 3.0.0.RELEASE. Since Spring Data MongoDB 3.0, the auto-index creation is disabled by default.
To enable auto-index creation, set spring.data.mongodb.auto-index-creation = true
or if you have custom Mongo configuration, override the method autoIndexCreation
