HTML Strip Char Filter
editHTML Strip Char Filteredit
The html_strip
character filter strips HTML elements from the text and
replaces HTML entities with their decoded value (e.g. replacing &
with
&
).
Example outputedit
POST _analyze { "tokenizer": "keyword", "char_filter": [ "html_strip" ], "text": "<p>I'm so <b>happy</b>!</p>" }
The |
The above example returns the term:
[ \nI'm so happy!\n ]
The same example with the standard
tokenizer would return the following terms:
[ I'm, so, happy ]
Configurationedit
The html_strip
character filter accepts the following parameter:
|
An array of HTML tags which should not be stripped from the original text. |
Example configurationedit
In this example, we configure the html_strip
character filter to leave <b>
tags in place:
PUT my_index { "settings": { "analysis": { "analyzer": { "my_analyzer": { "tokenizer": "keyword", "char_filter": ["my_char_filter"] } }, "char_filter": { "my_char_filter": { "type": "html_strip", "escaped_tags": ["b"] } } } } } POST my_index/_analyze { "analyzer": "my_analyzer", "text": "<p>I'm so <b>happy</b>!</p>" }
The above example produces the following term:
[ \nI'm so <b>happy</b>!\n ]
