/**
* A token filter factory to use with {@link AnalyzerDef} annotations
* to define an Elasticsearch tokenizer.
* <p>
* <strong>Caution:</strong> parameter values are interpreted as JSON, though using lenient parsing
* (quotes around strings may be left out in some cases, as when a string only contains letters).
* <p>
* Example:
* <pre><code>
* {@literal @}TokenizerDef(
* name = "custom-edgeNGram",
* factory = ElasticsearchTokenizerFactory.class,
* params = {
* {@literal @}Parameter(name = "type", value = "edgeNGram"),
* {@literal @}Parameter(name = "min_gram", value = "1"),
* {@literal @}Parameter(name = "max_gram", value = "10")
* }
* )
* </code></pre>
