Hello,
I recently looked into FTS 5. The documentation is clear and I was able to get it running with a small test database quickly. And the response times are awesome :-) My question: At least as I understand it at this point, FTS can only do prefix queries. If my database contains the words moon moonlight moonshine shine sunshine A FTS query like "moon*" will find all three terms starting with "moon" - very fast. But there is no way to find "moonshine" or "sunshine" by running a query for "shine" or "shine*" ? Currently I search using LIKE and there such 'contains' queries are easy. My users of course don't understand all this and want to find all words containing shine, wherever the term appears in the word. The only idea I had so far was to write my own tokenizer and to store each word with every possible 'sub-word': When "moonshine" is added to FTS, it is split into multiple words: moonshine oonshine onshine nshine shine . (maybe I limit this to a minimum of 2 or 3 characters). This of course produces a log of extra entries in FTS and may impact performance and database size. I hence wonder if this problem has been tackled already and if there is a "standard" solution.
