![]() Once you have identified a field that could benefit from indexing, you use the createIndex() method of MongoDB. Now that we have an understanding of what indexes are and when to use them, we can get into the method of creating one. Knowing when to use them is important, so making sure that you are adding them on database fields that are often being queried will keep your reads efficient without negatively impacting database size and write efficiency. Indexes are an incredibly useful way to optimize access to specific data that is often used as selection criteria in queries. Like the size of a book, adding too many indexes to a database also takes up space and has a detrimental effect on write operations on the database if not kept in check. While yes, it is faster to have an index for any data a query might use, there simply is data that doesn't need indexing. This is similar to an index in MongoDB and databases in general. There are many words such as "the" or "because" that are less useful to search for than "hippopotamus". At some point, the size of the book needed to accommodate indexing every word becomes ineffective. However, as you can imagine, the more lines of words in an index, the larger the book becomes. If it is always faster to use an index, then this seems beneficial. Keeping with our encyclopedia analogy, one might think to have an index line for every word in the book.
