Query by titles, IDs, and rich-text fields in Azure Boards and Azure DevOps

  • Makale

TFS 2018

When you want to find work items based on a keyword or phrase or a null text field, you can do so by filtering on single-line text (String), multi-line text (PlainText), and rich-text (HTML) fields. If you find that your queries take too long to return results, see Create a query/Best practices.

Supported operators and macros

Query clauses that specify a text or rich-text field can use the operators and macros listed in the following table.

Data type

Supported operators and macros

Rich-text (HTML)
Multi-line text strings (PlainText)

Contains Words, Does Not Contain Words, Is Empty1, Is Not Empty1

Single text (String)

= , <> , > , < , >= , <= , =[Field], <>[Field], >[Field], <[Field], >=[Field], <=[Field], Contains, Does Not Contain, In, Not In, In Group, Not In Group, Was Ever Macros: [Any], valid with the Work Item Type field and @Project2, valid with the Team Project field.

ID

= , <> , > , < , >= , <= , =[Field], <>[Field], >[Field], <[Field], >=[Field], <=[Field], In, Not In, Was Ever Macros: @Follows, @MyRecentActivity, @RecentMentions, @RecentProjectActivity valid with the ID field and In and Not In operators @Project2, valid with the Team Project field.

State and Work Item Type fields

= , <> , > , < , >= , <= , =[Field], <>[Field], >[Field], <[Field], >=[Field], <=[Field], Contains, Does Not Contain, In, Not In, In Group, Not In Group, Was Ever **Macros**:[Any]` valid with both fields.

Note

  1. The Is Empty and Is Not Empty operators are supported for Azure DevOps Server 2019 RC2 and later versions
  2. The system automatically defaults to filtering based on the current project. For more information, see Query across projects.

Use Contains words for string matches

When you want to filter on a string match, try using the Contains Words operator instead of Contains. The Contains Words operator runs a full-text search on the specified field, which is faster in most cases. Text string is limited to 100 characters.

While the Contains operator runs a table scan, which isn't only slower, but also consumes more CPU cycles. These CPU cycles contribute towards your resource consuming rate limit.

Note

The Contains Words operator makes use of SQL's full-text search indexing. When a new value is saved to a long-text field, SQL Server will:

  • Split the phrase into individual words
  • Remove any common words that don't really add value to a search (like "a" or "is" in English)
  • Convert words to their common stem (e.g. running, ran, and runner would get converted into "run", as they are all variations on that word)
  • Store these unique keywords in an index.

When a user then runs a query on this field using the Contains Words operator, the search will be run against the unique keywords stored in the index. For long-text fields, this makes searching much more efficient and quicker than doing a substring search. By default, SQL defines a "word" as a set of characters between punctuation. For example, periods signify the end of a word, but the period is not considered to be part of the word. Because the full-text search index contains keywords instead of exact phrases, you'll end up getting all the results that contain the same keywords, as determined by the indexing.

Keyword or phrase query with wildcards

Use Contains or Contains Words to list items that partially or exactly match the words or phrase that you enter.

Editor for flat list query for filtering key words.

Choose Contains or Does Not Contain to search against exact or partial matches of a word or phrase. Choose Contains Words or Does Not Contain Words to search against an exact phrase or to use the wildcard character, *. These operators use the full-text search index.

For example, specify Contains Words and inform* to filter on a text field that contains inform or information or informational.

Use wild card with Contains Words.

Tip

To understand how AND/OR clauses are grouped, see Create and save managed queries, Group clauses. To view the WIQL syntax for a query, install the WIQL query editor extension which allows you to see the WIQL version of any query editor entry.

Query for specific words and not others

Use Contains Words and Does Not Contain Words operators to list items that exactly match the words or phrase that you enter, and exclude other words or phrases. You can use these operators in combination and with the wildcard character (*).

In the following example, these operators filter work items for those items that contain the work Phase but not the word Phasor.

Undefined field value queries

You can find work items that have an undefined field value by using the equals operator (=) and leaving the Value for the field blank. For example, the following filters list all work items of type Task whose Activity field is blank.

Filter based on blank entries

To list work items based on a field that isn't blank, use the not operator (<>) and leave the Value blank.

Note

The ability to query for work items that don't have any tags attached to them is not a supported feature. If you'd like to up vote the request to support this feature, you can do so on our Developer Community page, Be able to search for empty tags.

Category-based queries

To filter work items based on the category they belong to, use the In Group operator. For example, the following filter criteria returns all work items that are in the current project, assigned to the team member, and defined as belonging to the Bug Category.

Query clause to find work items by category

What items appear in the Requirement or Task categories?

The default assignments of work item types to each category are listed below for each process.

Process Requirement category Task category
Basic Issue Task
Agile User Story Task
Scrum Product Backlog Item, Bug Task
CMMI Requirement Task

Each team can determine if the Bug work item type appears in either the Requirement or Task category. See Show bugs on backlogs and boards. You can add custom work item types to a backlog. For more information, see Add or modify a work item type, Add a custom WIT to a backlog or board.

Query for work items that you're following

You can use the @Follows macro to filter a list based on work items you're following along with other query filters.

For example, the following query shows how to query across all projects for active work items that you're following. You use the ID field and the In operator with the @Follows macro.

Query Editor, with ID In @Follows query clause

Query for recent work item activity

You can use the following macros to list work items based on recent activity:

  • @MyRecentActivity: List items you've recently viewed or modified.
  • @RecentMentions: List items you were added to via an @mention in the last 30 days.
  • @RecentProjectActivity: List items that have been recently created or modified in your project.

Specify the ID field and either the In or Not In operators.

For example, the following query shows how to query for work items that you've recently viewed or modified.

Common fields for most work item types

The following table describes common fields used to filter queries. The ID fields uniquely identify work items in a list. Use the Title field to distinguish the work item from all others of the same type. The Description and other rich-text (data type=HTML) fields provide additional information that is needed to implement work and track changes. After a work item is created, you can modify all fields except for the ID. When you add and save a work item, the ID is assigned by the system and cannot be changed.

Note

The system automatically indexes all long-text fields with a data type of PlainText and HTML fields for full-text search. This includes the Title, Description, and Steps to Repro fields. For more information and server and collation requirements applicable to on-premises Azure DevOps, see Query fields, operators, values, and variables - Full-text and partial word searches.

Acceptance Criteria 1

A description of the criteria to be met before the bug or product backlog item can be closed.

Before work begins on a bug or product backlog item, the criteria for customer acceptance should be described as clearly as possible. Conversations between the team and customers to define the acceptance criteria helps ensure that your team understands your customers' expectations. The acceptance criteria can be used as the basis for acceptance tests so that you can more effectively evaluate whether an item has been satisfactorily completed.
