Constructs a Lucene Analyzer using the CustomAnalyzer builder. Under the hood it uses the factory classes TokenizerFactory, TokenFilterFactory, and CharFilterFactory. The factories are loaded with java.util.ServiceLoader.

Analysis component description is of shape: {ComponentNameKeywordOrString MapOfParams} Or when the MapOfParams is empty then only ComponentNameKeywordOrString can be passed.

If needed factories can be passed as arguments in shape: {STRING CLASS}

Example: {:tokenizer {"standard" {:maxTokenLength 4}} :char-filters [{"patternReplace" {:pattern "foo", :replacement "foo"}}] :token-filters [{"uppercase" nil} {"reverseString" nil}] :config-dir "."}

Short notation: {:tokenizer :standard :char-filters [:htmlStrip] :token-filters [:uppercase]}

opts map can specify these keys:

• config-dir: path to directory from which resources will be loaded, default '.'
• classpath-resources: when true and :config-dir is nil then loads resources from classpath
• char-filters: list of char filter descriptions
• tokenizer: tokenizer description, default 'standard' tokenizer
• token-filters: list of token filter descriptions
• position-increment-gap: specify position increment gap
• offset-gap: specify offset gap
• namify-fn: function that changes the string identifier of the service name, e.g. str/lowercase, default: identity
