including a number in Launchpad bugs search causes search to fail
I'm trying to understand the behavior of the Launchpad "Search Bug Reports" feature.
I'm using the search box on
https:/
, and attempting to locate a particular bug, in this case LP #658227. The description of that bug is currently set to
upgrade process does not upgrade underlying BDB format from 4.7 to 4.8 (so slapd aborts with "Program version 4.8 doesn't match environment version 4.7" error message)
(The bug is still open/active, and is not marked as a duplicate.)
If I leave the radio button next to "All projects" selected, and enter "Program version 4.8
doesn't match environment" into the search box (cut-and-pasting from the bug description to make sure the spelling is correct)... I get back no bugs at all.
However, if I go Back and then remove the "4.8" from my search text, so that I have "Program version doesn't match environment"... I do get back my bug (as well as two others that also contain a similar message.
Why does adding the number to the search string cause the search to fail?
Is there any documentation about how the search text is "parsed" in the Launchpad bug search?

Hi Nathan,
It looks like a bug, so I've filed bug 659870 about it.
Thanks for letting us know!
Gavin.
Great, thanks.
I'm still curious to know if there is any documentation anywhere about how the bug search text is parsed/used.
In my experiments, it seems that the search hits were bugs that had most-but-
Is there any way to do an exact phrase search, or to eliminate bugs that include a particular word, etc.?

In lp:launchpad (or lp:launchpad/devel, which is the more common development target for us) there's a _buildSearchTex
So are you saying that the search text I enter is passed almost directly to the PostgreSQL full-text search (except for the quoting that I see done there in _buildSearchTex
In any case, I take it that you don't know of any help page documenting the operation of the Bug Search from the users point of view? If not, I might go ahead and open a wishlist bug about that, too.

Yes, that's how I understand it.

I don't know of any. I quickly checked https:/
there's no sign of any there. It would be great if you could file a
bug about it.
Okay, thanks, I'll do that.
All right, I've opened LP: #660283 regarding the lack of documentation for the bug-search expressions.
Thanks Gavin Panella, that solved my question.
