Hi,

Is anybody working on implementing n-gram search functionality for
text type data? tsearch2 is great for long text but it's not
appropreate for short (10-100 bytes) text data. What I want to achieve
is a fast partial match search using indexes, i.e. foo ~ 'bar' or foo
LIKE '%bar%' type matching.
