Compound Word Token Filter

edit

Token filters that allow to decompose compound words. There are two types available: dictionary_decompounder and hyphenation_decompounder.

The following are settings that can be set for a compound word token filter type:

Setting	Description
`word_list`	A list of words to use.
`word_list_path`	A path (either relative to `config` location, or absolute) to a list of words.
`hyphenation_patterns_path`	A path (either relative to `config` location, or absolute) to a FOP XML hyphenation pattern file. (See http://offo.sourceforge.net/hyphenation/) Required for `hyphenation_decompounder`.
`min_word_size`	Minimum word size(Integer). Defaults to 5.
`min_subword_size`	Minimum subword size(Integer). Defaults to 2.
`max_subword_size`	Maximum subword size(Integer). Defaults to 15.
`only_longest_match`	Only matching the longest(Boolean). Defaults to `false`

Here is an example:

index :
    analysis :
        analyzer :
            myAnalyzer2 :
                type : custom
                tokenizer : standard
                filter : [myTokenFilter1, myTokenFilter2]
        filter :
            myTokenFilter1 :
                type : dictionary_decompounder
                word_list: [one, two, three]
            myTokenFilter2 :
                type : hyphenation_decompounder
                word_list_path: path/to/words.txt
                max_subword_size : 22
