Stop Token Filter

Stop Token Filter

edit

A token filter of type stop that removes stop words from token streams.

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

Setting	Description
`stopwords`	A list of stop words to use. Defaults to english stop words.
`stopwords_path`	A path (either relative to `config` location, or absolute) to a stopwords file configuration. Each stop word should be in its own "line" (separated by a line break). The file must be UTF-8 encoded.
`enable_position_increments`	Set to `true` if token positions should record the removed stop words, `false` otherwise. Defaults to `true`. [0.90.3] Deprecated in 0.90.3. Removed in Lucene 4.4
`ignore_case`	Set to `true` to lower case all words first. Defaults to `false`.
`remove_trailing`	Set to `false` in order to not ignore the last term of a search if it is a stop word. This is very useful for the completion suggester as a query like `green a` can be extended to `green apple` even though you remove stop words in general. Defaults to `true`.

stopwords allow for custom language specific expansion of default stopwords. It follows the _lang_ notation and supports: arabic, armenian, basque, brazilian, bulgarian, catalan, czech, danish, dutch, english, finnish, french, galician, german, greek, hindi, hungarian, indonesian, italian, norwegian, persian, portuguese, romanian, russian, spanish, swedish, turkish.
