在 meta-toolkit 的 config.toml 中配置默认​​链

Question

我想在 meta-toolkit 中使用默认过滤器链配置 config.toml 文件，但要指定每个过滤器。我计划对一些过滤器进行修改，因此我想要一个基线过滤器链。

我试过以下属性：

[[analyzers]]
method = "ngram-word"
ngram = 1
    [[analyzers.filter]]
    type = "icu-tokenizer"

    [[analyzers.filter]]
    type = "lowercase"

    [[analyzers.filter]]
    type = "alpha"

    [[analyzers.filter]]
    type = "length"  
    min = 2
    max = 35

    [[analyzers.filter]]
    type = "list"
    filename = "../data/lemur-stopwords.txt"

    [[analyzers.filter]]
    type = "porter2-stemmer"

    [[analyzers.filter]]
    type = "empty-sentence"

我得到：

token_stream_exception: what(): file required for list_filter config

Answer 1

属性应该是文件而不是文件名。

[[analyzers.filter]]
type = "list"
file = "../data/lemur-stopwords.txt"
