+Given a predicate, filter out all elements that don't satisfy that predicate.
+May also be used to filter based on an inequality with a given value based
+on the comparison ordering of the element.
+
+## Examples
+**Example 1**: Filtering with a predicate
+
+```java
+PCollection<String> allStrings = Create.of("Hello", "world", "hi");
+PCollection<String> longStrings = allStrings
+ .apply(Filter.by(new SerializableFunction<String, Boolean>() {
+ @Override
+ public Boolean apply(String input) {
+ return input.length() > 3;
+ }
+ }));
+```
Review comment:
I agree. But @davidcavazos is replacing these samples with his colab in the
new few months, so it might make more sense to invest time into that.
These snippets were written by @kennknowles and @bjchambers a while ago.
