Custom Analyzeredit

An analyzer of type custom that allows to combine a Tokenizer with zero or more Token Filters, and zero or more Char Filters. The custom analyzer accepts a logical/registered name of the tokenizer to use, and a list of logical/registered names of token filters. The name of the custom analyzer must not start with "_".

The following are settings that can be set for a custom analyzer type:

Setting Description

position_offset_gap

An optional number of positions to increment between each field value of a field using this analyzer.

        analyzer :
            myAnalyzer2 :
                type : custom

                filter : [myTokenFilter1, myTokenFilter2]
                char_filter : [my_html]
                position_offset_gap: 256
        tokenizer :
            myTokenizer1 :

                min : 0
                max : 2000

              my_html :
                type : html_strip
                escaped_tags : [xxx, yyy]
