Hi there, As I know we have 3 steps on text field when document with text field is indexed in elasticsearch. First - Char-filter process, Second - Tokenizing process, Third - Token filtering process I have the following mapping in my index: "mappings": { "properties": { "field1": { "type": "text", "analyzer": "whitespace" }, } } So I am wandering what the Whitespace analyzer exactly does on text field on this exact situation? Is there any Char-filter process by default on field1? As I know, if I don't set it, there will not be any char-filter and first step will be tokenizing process by default,Then tokenizing process only split text by space, After that if I don't set token filter, it will be default just lowercase filter. Is it correct or not ? ---

Yes, you are exactly right. You can see how the whitespace analyzer has been defined [in the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-whitespace-analyzer.html#_definition_7). The whitespace analyzer has no character filters, so the first step is the [whitespace tokenizer](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-whitespace-tokenizer.html), which breaks strings on whitespace. Finally, there are no token filters. So that's really all that this analyzer does: it breaks strings on whitespace. ---

Thanks such a quick answer, But what about token-filter ? isn't there any lowercase token filter after tokenizing process ? ---

No, there are no token filters in this analyzer. If you would like to use the whitespace tokenizer in combination with the lowercase token filter, you would have to create a [custom analyzer](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-custom-analyzer.html) that combines these two. ---

Abdon one more question please, It is index time analyzer in my example above, right ? And at the search time, is it necessary to reference which analyzer could be used with that field above? ---

By default, when you query a field, Elasticsearch will apply the analyzer that's defined in the mapping to the query terms. There is no need to specify the analyzer at search time. ---
