Sourmash gather returns results whereas search returns nothing

[mw55309]

Sorry if this is a dumb question, maybe I am mis-interpreting the functions.

I have a genome (not reads, the genome). For the purposes of this test, I am using ecoli, so I have ecoli.fa and ecoli.sig. I am using the signature to search against the genbank database you offer for download.

I am back on version 2.0.0a6 because if I upgrade to 2.0.0a9 I have to migrate the index ;-)

sourmash gather produces results:

sourmash gather sourmash/ecoli.sig ../genbank-d2-k31.sbt.json --scaled 1000 -o ecoli.gather 

overlap     p_query p_match
---------   ------- --------
4.5 Mbp     100.0%  100.0%      CP011320.1 Escherichia coli strain SQ...

found 1 matches total;
the recovered matches hit 100.0% of the query

And sourmash search does not:

sourmash search sourmash/ecoli.sig ../genbank-d2-k31.sbt.json --scaled 1000 -o ecoli.search

0 matches:
similarity   match
----------   -----

Is this expected? If so, why? What am I mis-understanding?

Cheers

Sorry for delay in response - this is hopefully the bug we fixed in #484. If you get a chance to test, please do!
