Question

Given the following tables:

create table index(name text, docid int);
create virtual table docs using fts4();

The following query works as intended when querying for a single token (for example: march, or bad):

select name from index where docid in (select docid from docs where docs match ?)

But how can I query for more than one token (say, bad bed)? Binding the string bad bed directly does not work (always selects nothing), neither surrounding the placeholder or the string with double quotes, nor using AND to MATCH each token separetly (this last one throws an error).

Using intersect does work, but it’s clunky and innefficient when searching for many tokens:

select name from index where docid in (
    select docid from docs where docs match ?
    intersect
    select docid from docs where docs match ?
    intersect
    ...
)

Each ? is paired with a single token.
