mu find does not find matching messages

[Laurence Rochfort]

Hello,

I'm running v0.9.16, built from git.

I have found that mu isn't finding messages containing known strings. Can people please confirm I'm searching correctly?

I have a messages that contains the following string:

ca-ulndev-swd1.XX.XXX.com  : Dev server.

I search like this:

$ mu find ca-ulndev

mu: no matches for search expression (4)

I've tried various combinations of wildcards and quotes, but still get no results.

Any advice?

Cheers,

Laurence.

Does mu find ca-ulndev* work?


Jostein

[Laurence Rochfort]

Unfortunately not. I get exactly the same error message.

[Jostein Berntsen]

Can you try this with quotes?

mu find 'ca-ulndev*'

Or else run with "--format=xquery" to check the output.

Still no results unfortunately:

~ $ mu find ca-ulndev --format=xquery

Xapian::Query((Hca_ulndev:(pos=1) OR Bca_ulndev:(pos=1) OR Cca_ulndev:(pos=1) OR Eca_ulndev:(pos=1) OR Jca_ulndev:(pos=1) OR Fca_ulndev:(pos=1) OR Mca_ulndev:(pos=1) OR Yca_ulndev:(pos=1) OR Ica_ulndev:(pos=1) OR Sca_ulndev:(pos=1) OR Tca_ulndev:(pos=1) OR Uca_ulndev:(pos=1) OR Xca_ulndev:(pos=1) OR Dca_ulndev:(pos=1) OR Gca_ulndev:(pos=1) OR Pca_ulndev:(pos=1) OR Zca_ulndev:(pos=1) OR Vca_ulndev:(pos=1) OR Wca_ulndev:(pos=1)))

The search engine / query parser that mu4e uses (Xapian) treats dashes
and dots as word separators, so sadly, this is expected to not work;
there's no escaping mechanism either.

Kind regards,
Dirk.

Thanks Dirk.

For clarification, is it dashes in just the query that cause problems, or dashes in the content too?

Mu does a few tricks to try to get the around the limitations of the
query parser by "massaging" the content a bit when storing it (this
includes e.g. removing accents etc.), and similarly with the queries.

It's not perfect though, as you've seen.

Cheers,
