When starting out with FileMaker, there's rarely the situation where you receive any "before you get started" advice. This is because working in FileMaker is like picking up a blank canvas and having someone say "Go for it! Paint something."

Essentially, you need to know what the tools are, how you use them, what can be accomplished and how certain decisions might affect you. So, when it comes to field indexing, you might not know the default settings could potentially cause your solution to become bigger than it should - without any benefit to performance.

While searching an indexed field vs. an unindexed one becomes somewhat obvious - the search may be slower than expected - it's the fact that every field, by default, can optionally enable its index that makes things interesting with regards to file size and, to a certain degree, some efficiency.

In this video I break down exactly how you can see what is going on with each specific field index and what the true difference is between a value index and a word index. You may even find out that your primary key fields are actually able to index more than they really should!
