If you want to remove some content generated by FSCrawler, I'd recommend to use an ingest pipeline which removes the fields you don't want.

If I only want to change the field type of file tltle from `keyword` to `text`, is the ingest necessary or just modifying the mapping will work? Because I want to do full-text search to both content and title.

Just modify the mapping if needed in that case.
