Except a trigram sequence can speed up LIKE regardless of the position of characters in a column. FTS5 won't (I don't think) support substrings within a longer string, only prefix or exact matches of tokens. For example: ``` SELECT * FROM tab WHERE col LIKE '%cot%' ``` Will return 'cot', 'rural cottage', 'cottage cheese', and 'Scott' (among other possibilities). I don't think FTS5 would support that sort of a search, where cot might be embedded within a word as it is in my name.
