StopWordFilter

StopWordFilter is an English language stop word list filter, any words contained in the list are not stored in the index.

This is intended to be used in the ElmTextSearch token processing pipeline.

Input tokens to create stop word filters should be full words, if you dont know the transform steps for index or if you use the list with different sets of transforms.
If you know the exact transform process of your Index you can prerun the transform process to generate your word list, which in theory might make it a little more efficient.
It is more efficient to merge all your stop words into a single stop word filter.
