Yo, lemme drop some knowledge on you all, 'Bout filter expressions, standin' tall. They're powerful tools, that's no lie, But restrictions exist, so listen up, why?

The Syntax Struggle

First things first, the grammar's key, Incorrect syntax? You won't agree. Parentheses, brackets, all in place, Or your filter's gonna fall out of grace.

Operator Overload

Operators matter, you gotta know, Mismatched types? Watch the errors flow. Strings and numbers, don't mix 'em up, Or your filter's gonna start to slump.

Data Type Dilemma

Data types are critical, understand, Mixing them up? It's out of hand. Integers, strings, dates, all so neat, Using the wrong one? Your query's incomplete.

Case Sensitivity Concerns

Case sensitivity, it's a real thing, "Apple" and "apple" won't be the same swing. Be consistent, yo, or your results will be skewed, A mismatch in case, ain't gonna do.

Function Familiarity

Functions are vital, let's make it plain, Using them wrong, it's all in vain. Check the parameters, type and amount, Incorrect arguments? You're getting bounced.

Nested Nesting Nightmare

Nesting too deep? It's a risky game, Your filter's complexity could bring you shame. Keep it simple, keep it clear, Avoid the chaos, that much is clear.

Performance Penalties

Complex filters? They can really slow, Performance penalties, everyone knows. Optimize your filters, think before you leap, Efficiency's key, while you're asleep.

Security Concerns

Security matters, that's the bottom line, Avoid SQL injection, that's the design. Sanitize inputs, it's a must to do, Secure your data, it's vital for you.

Conclusion: Keep it Clean

So, next time you're writing a filter, Remember these restrictions, that's the filter. Keep it clean, keep it tight, And your data will shine ever so bright! Word.
