AnalyzerProperties Properties

Optional. When true, accented characters are preserved. When false, accented characters are converted to their base characters.

The case to use when normalizing the text. Possible values: "lower" to convert to all lower-case characters "upper" to convert to all upper-case characters "none" to not change character case (default)

A locale in the format language[_COUNTRY][.encoding][@variant] (square brackets denote optional parts), e.g. "de.utf-8" or "en_US.utf-8". Only UTF-8 encoding is meaningful in ArangoDB. The locale is forwarded to ICU without checks. An invalid locale does not prevent the creation of the Analyzer.

Turn Stemming ON or OFF. If true, the analyzer stems the text, treated as a single token, for supported languages. Stemming support is provided by Snowball, which supports the languages listed at: https://www.arangodb.com/docs/stable/analyzers.html#stemming

An Analyzer is capable of removing specified tokens from the input. It uses binary comparison to determine if an input token should be discarded. It checks for exact matches. If the input contains only a substring that matches one of the defined stopwords, then it is not discarded. Longer inputs such as prefixes of stopwords are also not discarded.
