The query page is broken down into the following sections:
Text Search Options
The Bottom Of The Form
"I already know how to use Bugzilla, but would like information about Bugzilla and the author of this document."
"Ok, I am almost certain the bug I discovered isn't in Bugzilla, how do I submit the bug?" - Read the guidelines first!
Back to the Query. If you typed anything in the forms already, you might want to hit back on the
browser. When you are all done reading, do a sample query!
The resolution field indicates what happened to this bug.
No resolution yet: All bugs which are in one of the "open" states (meaning the state
has no associated resolution)
have the resolution set to blank. All other bugs
will be marked with one of the following resolutions.
The platform field is the hardware platform against which the bug was reported. Legal
platforms include but are not limited to:
Note: Selecting the option "All" does not select bugs assigned against all platforms. It
merely selects bugs that occur on all platforms.
The operating system field is the operating system against which the bug was reported. Legal
operating systems include but are not limited to:
Note that the operating system implies the platform, but not always.
For example, Linux can run on PC and Macintosh and others.
The priority field describes the importance and order in which a bug should be
fixed. This field is utilized by the programmers/engineers to
prioritize their work. The priorities are from P1 (Most important) to P5
The Severity field describes the impact of a bug.
To search for bugs associated with an email address:
You can look for up to two different email addresses. If you specify
both, then only bugs which match both emails will show up. This is useful to
find bugs that were, for example, created by Ralph and assigned to
You can also use the drop down menus to specify whether you want to
match addresses by doing a substring match, by using Regular
Expressions, or by exactly matching a fully specified email address.
In this section, you can enter values that are searched for in all the bugs (or whatever you
limit the bugs to in other fields).
You might want to look at Bugzilla Text Searching
to see info on Regular Expressions and text searching. The box next to these fields decides
how a match will be determined.
This lets you search the summaries. The summary is one line that attempts to sum up the bug.
This lets you search comments. Comments can be added by anybody. Comments are the largest
searchable area in most bugs. If you really want to find a lot of matches, search the comments.
Note:Because comments can get quite extensive in bugs, doing this particular type
of query can take a long time.
This lets you search the url field. This contains the url of the web page the bug is
This lets you search the bug's status whiteboard. The status whiteboard contains general
information that engineers add.
Module options are where you select what product, module and version the bugs you want to
find describe. Selecting one or more of the products, versions, components, or milestones will limit your search.
Although all subprojects within the Mozilla project are similar, there are several seperate
products being developed. Each product has its own components.
This is simply the version that the bugs you want to find are marked for.
Many of the bugs will be marked for another version and will have their milestones
entered instead (milestones explained below).
Each product has components, against which bugs can be filed. Components are parts of
the product, and are assigned to a module owner. The following lists
components and their associated products:
Choosing this section lets you search through bugs that have their target milestones set to certain
values. Milestones are kind of like versions. They are specific tentative dates where a massive
phasing out of bugs occur and a relatively stable release is produced. For example, Mozilla.org had milestones in the
form of "M10" or "M18", but now are in the form of "Mozilla0.9". Bugzilla milestones are in the form of "Bugzilla 2.12",
"Bugzilla 2.14", etc.
Inclusion/Exclusion options is a powerful section that gives you the ability to include and
exclude bugs based on values you enter.
[Only, Exclude] bugs numbered [text]
This lets you put in a comma-delimited list of bugs you want to have your results chosen from, or those
of which you want to exclude. It would be nice in the future if you could type in ranges, i.e. [1-1000] for 1
to 1000. Unfortunately, you cannot do that as of now.
Changed in the last [text] days
Lets you specify how many days ago - at maximum - a bug could have changed state.
At least [text] votes
With this, you can choose how many votes - at minimum - a bug has.
Where the field(s) [fields] changed to [text]
With this, you can specify values to search for in fields that exist in the bug If you choose
one or more fields, you have to fill out one of the fields to the right. It might
be difficult to figure out what these fields mean if you are a newbie to the query.
They match various fields within the bug information. Optionally, you can
also enter what value you want the field to have changed to if you only entered one field.
For instance, if the bug changed who it was assigned to from email@example.com
to firstname.lastname@example.org , you could enter in
assigned_to changed to email@example.com.
During dates [text] to [text]
Here, you can choose what dates the fields changed. "Now" can be used as an entry. Other entries should be in
mm/dd/yyyy or yyyy-mm-dd format.
The Bugzilla query page is designed to be reasonably easy to use.
But, with such ease of use always comes some lack of power. The
Advanced Querying section is designed to let you do very powerful
queries, but it's not the easiest thing to learn (or explain).
The Advanced Query (or Boolean Chart) starts with a single "term". A term is a
combination of two pulldown menus and a text field.
You choose items from the menus, specifying:
Field 1: Where to look for the search term
Field 2: How to determine what is a match
Field 3: What the search term is
The real fun starts when you click on the "Or" or "And" buttons. If
you push the "Or" button, then you get a second term right under
the first one. You can then configure that term, and the result of
the query will be anything that matches either of the terms.
You can push the "And" button, and get a new term below the
original one - seperated by the word "AND", and now the result of
the query will be anything that matches both sets of terms.
You can keep clicking "And" and "Or", and get a page with many
terms. "Or" has higher precedence than "And". You
can think of the lines of "Or" as having parenthesis around them.
The most subtle thing to notice is the "Add another boolean chart" button.
This is almost the same thing as the "And" button. You want to use this when
you use one of the fields where several items can be associated
with a single bug - including: "Comments", "CC", and all the
"changed [something]" entries. If you have multiple terms that
all are about one of these fields (such as one comment), it's ambiguous whether they are
allowed to be about different instances of that field or about only that one instance. So,
to let you have it both ways, they always mean the same instance,
unless the terms appear on different charts.
For example: if you search for "priority changed to P5" and
"priority changed by person@addr", it will only find bugs where the
given person at some time changed the priority to P5. However, if
what you really want is to find all bugs where the milestone was
changed at some time by the person, and someone (possibly someone
else) at some time changed the milestone to P5, then you would put
the two terms in two different charts.
So you have gotten all that down, but "What is this junk at the bottom of the form?"
You can remember the current query as the default query page that is pulled up whenever you are
logged on. There is also an ability to choose how you want your results sorted. When finished,

The Bug Reporting Guidelines
My main motive for writing this was to help the engineers by giving new Bugzilla users a way to learn how to use the Bugzilla Query form. I
had done a rewrite of query.cgi, so I said, "What the heck, I'll write this too".
You probably looked at the Query page and said, "This page looks too difficult. Now that
I think about it, I don't really need to do a query". It is important to make sure that a bug
doesn't have a duplicate before submitting it, as is stated clearly in
The Bug Reporting Guidelines.
The people reading your bugs are busy and usually swamped with bugs. Therefore, you are doing everyone
a huge favor to search for a duplicate.
Ok. So lets find a bug! We'll borrow the Mozilla.org database because it's handy.
First, lets make a
copy of the query window so you can easily switch between this document and the query.
Do the following:
One of the results should have been bug 22775 - [RFE] AutoScroll/Panning support...
