The documentation of index_sp says that “Both sentences and paragraphs increment the keyword position counter by 1”.
That increment makes searches like “hello world” not work across the boundary which I don’t like at all, especially since boundary detection can’t be changed. Still I do want to have index_sp enabled to be able to use SENTENCE and PARAGRAPH operators.
So I’d like to have an option similar to phrase_boundary_step which would allow setting sentence/paragraph boundary word position increment to zero, instead of the default 1.
