=head1 Introduction

The Query Builder is RT's search engine. It lets you find tickets matching
some (potentially very complex) criteria. There are loads of criteria you can
specify in order to perform a search. Strategies for narrowing your searches
to find exactly what you're looking for (and no more) are discussed below.

The Query Builder is the heart of reporting in RT, which is covered in the
L<Dashboard and Reports|docs/dashboards_reporting.pod> document.

To follow along with the examples, go to
L<issues.bestpractical.com|http://issues.bestpractical.com> and try the
searches yourself.

=head1 Example

Let's look for tickets in the "RT" queue (RT's bugtracker for itself) that have
been resolved in the last year. (These examples assume it's currently mid June,
2015). To do that, we specify the search criteria (Queue is RT, Status is
resolved, and Resolved after 2014-06-15) in the upper left hand section of the
Query Builder.

=for html <img alt="Search Criteria"
src="images/search-criteria.png">

=for :text [Search Criteria F<docs/images/search-criteria.png>]

=for :man [Search Criteria F<docs/images/search-criteria.png>]

RT also has two meta-statuses, 'active' and 'inactive'. By selecting either of
these from the status dropdown of the query builder, you will no longer need
to explicitly list all of the active or inactive statuses or manually enter
the queries: "Status = '__Active__'" or "Status = '__Inactive__'".

The sets of active and inactive statuses for a queue are defined by the
associated lifecycle. Active tickets are those listed for the 'active' and
'initial' configurations. Inactive tickets are those defined as 'inactive'.
For the default RT lifecycle, for example, the active statuses are new, open,
and stalled, and the inactive statuses are resolved, rejected and deleted. See
F<docs/customizing/lifecycles.pod> for more information.

Now that I've selected some criteria, I can click either Add These Terms or
Add These Terms and Search. I'll click the former:

=for html <img alt="Added Terms"
src="images/added-terms.png">

=for :text [Added Terms F<docs/images/added-terms.png>]

=for :man [Added Terms F<docs/images/added-terms.png>]

The upper right hand side presents all the logic we've specified. This view is
a nice way proofread your search: Have you captured everything you want? Are
there things you'd maybe prefer to leave out for now?

It turns out I've changed my mind. I actually don't want to restrict the search
to just the RT queue. I want to see all the tickets in issues.bestpractical.com
(which also includes feature requests, RTIR, etc) that have been resolved
within the past year. To adjust the search, click on 'AND Queue = RT' and press
Delete:

=for html <img alt="Delete Term"
src="images/delete-term.png">

=for :text [Delete Term F<docs/images/delete-term.png>]

=for :man [Delete Term F<docs/images/delete-term.png>]

Your search should now look like this:

=for html <img alt="Deleted Term"
src="images/deleted-term.png">

=for :text [Deleted Term F<docs/images/deleted-term.png>]

=for :man [Deleted Term F<docs/images/deleted-term.png>]

Now, finally, to make the search go, you can either press 'Add these terms and
Search' (provided there's no new content in the Query Builder), or scroll all
the way down and press 'Update format and Search'. This search should turn up
a full page of tickets. Here's the top portion of the list:

=for html <img alt="Search Results"
src="images/search-results.png">

=for :text [Search Results F<docs/images/search-results.png>]

=for :man [Search Results F<docs/images/search-results.png>]

This is the default view of your results. However, like nearly everything in RT,
it's configurable. You can select additional columns to appear in your results,
eliminate columns you don't find useful, or reorder them. To start, notice that
at the bottom of the query builder page there are two panes: Sorting and Display
Columns.

=for html <img alt="Sorting and Display Columns"
src="images/sorting-display-columns.png">

=for :text [Sorting and Display Columns
F<docs/images/sorting-display-columns.png>]

=for :man [Sorting and Display Columns F<docs/images/sorting-display-columns.png>]

There is more than one option for Sorting so that you can break apart tickets
with the same search values into a meaningful order. For example, let's say you
start off by sorting tickets in a search by their owner. Since you've only
specified to sort by owner, RT doesn't order the tickets owned by the same user
in a meaningful way. This is where the multiple sort criteria comes in handy.
You can use a second sorting criteria to sort within the set of tickets owned by
a single user. For example, you could add a sort by due date to see tickets
sorted first by owner, and then tickets with the same order are ordered by due
date.

The Display Columns tab allows you to add or eliminate information displayed in
the results of your search. NEWLINE indicates a line break, or new row, in how
the results are displayed. NBSP for adding an empty column (such as what shows
up underneath id in the following screenshot).

Here is a search with NEWLINE where it is by default:

=for html <img alt="With NEWLINE"
src="images/with-newline.png">

=for :text [With NEWLINE F<docs/images/with-newline.png>]

=for :man [With NEWLINE F<docs/images/with-newline.png>]

Notice that the structure of the data that's displayed is stacked: Subject on
top of Requestor, Status on top of Created, etc.. Because we're displaying a
lot of information (10 fields for each ticket), having the NEWLINE is
important for the results more comprehensible.

Here is that same search but without the NEWLINE:

=for html <img alt="Without NEWLINE"
src="images/without-newline.png">

=for :text [Without NEWLINE F<docs/images/without-newline.png>]

=for :man [Without NEWLINE F<docs/images/without-newline.png>]

The same pieces of information are now spread across the display next to one
another, which can be harder to read. So when you tell RT to display a lot of
columns, it's usually worth adding a well-placed NEWLINE.

And there are the basics of the query builder! To implement these basics to
build reports, please see the Dashboard & Reports document. For definitions of
piece of RT metadata, please see the Definitions of Ticket Metadata document.
