Introduction to Elasticsearch Analyzers.
Here we also have the option to use a default tokenizer or a custom tokenizer to suit our specific purpose. A simple tokenizer would split the input string whenever it encounters a whitespace or a punctuation. Also, by using custom tokenizers like pattern tokenizers, we can look for patterns and split the input string accordingly. The next process in line is the filtering of the terms generated after tokenisation. The terms are passed through a token filter, which transforms the terms to the standard the user wants. In some cases we need to just lower case the terms after tokenisation. Although in some cases we might need to remove commonly used words such as athefor, etc. So we apply the required token filter to it and we get the required tokens generated. The entire process happening in an analyzer can be explained using the flow diagram below.: The role of Elasticsearch analyzers.
