An analzyser processes indexed data so that it is relevant to text searches. It is made up of three parts: zero or more character filters, one tokenizer, and zero or more token filters. The character filter preprocess the stream of characters before passing the stream to the tokenizer. The tokenized stream is passed into a tokenizer.

There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, “I don’t see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it.”
For now, it’s good to “go away and think”. There’s probably a lot of wisdom in understanding how you got to a certain point, or what might cause someone to put a gate across a road—maybe then the cattle grate is the right tool.
