Before you read this document, it is important that you understand the concepts of Data Catalog such as data entry, tags and tag templates, and other kinds of metadata. See [What is Data Catalog?](/data-catalog/docs/concepts/overview).\n\nTo launch a Data Catalog search query in the\nGoogle Cloud console, go to the Data Catalog **Search** page and\nselect **Data Catalog** as the search mode.\n\n[Go to Search](https://console.cloud.google.com/dataplex/search)\n\nSimple search\n-------------\n\nIn its simplest form, a Data Catalog search query comprises a single predicate. Such a\npredicate can match several pieces of metadata:\n\n- A substring of a name, display name, or description of a data asset\n- Exact type of a data asset\n- A substring of a column name (or [nested column](/bigquery/docs/nested-repeated) name) in the schema of a data asset\n- A substring of a project ID\n- The value of a public tag, the name of a public tag template, or a field name in a public tag template attached to a data entry.\n- (Preview) A string for an email address or name for a data steward\n- (Preview) A string from an overview description\n\nThe simple search does not support tag template fields of type `datetime`.\n\nFor example, the predicate `foo` matches the following entities:\n\n- Data asset with the `foo.bar` name\n- Data asset with the `Foo Bar` display name\n- Data asset with the description `This is the foo script.`\n- Data asset with the exact `foo` type\n- Column `foo_bar` in the schema of a data asset\n- Nested column `foo_bar` in the schema of a data asset\n- Project `prod-foo-bar`\n- Public tag template named `foo`, data entries tagged with the `foo` tag template, tag template display name of `foo`, tag template field name of `foo`, and tag field value of `foo` in a string, enum, or rich text.\n- (Preview) Data asset with a data steward called `foo`.\n- (Preview) Data asset with an overview containing the word `foo`.\n\nTo know more about the roles and permissions to view public and private tags, see [Roles to view public and private tags](/data-catalog/docs/concepts/iam#roles_to_view_public_and_private_tags).\n\nQualified predicates\n--------------------\n\nYou can qualify a predicate by prefixing it with a key that restricts the\nmatching to a specific piece of metadata.\n\nAn equal sign (`=`) restricts the search to an exact match.\n\nA colon (`:`) after the key matches the predicate to either a substring or token within\nthe value in search results.\n\nTokenization breaks the stream of text up into a series of tokens, with\neach token usually corresponding to a single word.\n\nFor example:\n\n- `name:foo` selects entities with names that contain the `foo` substring: `foo1` and `barfoo`.\n- `description:foo` selects entities with the `foo` token in the description: `bar and foo`.\n- `location=foo` matches all data assets in a specified location with `foo` as the location name.\n\n| **Note:** You can only search for an exact `type=foo`, `system=foo`, `location=foo`, or `orgid=number`. The corresponding predicate keys can't be followed by a colon.\n\nData Catalog supports the following qualifiers:\n\nLogical operators\n-----------------\n\nA query can be comprised of several\npredicates with logical operators. If you don't specify an operator, logical\n`AND` is implied. For example, `foo bar` returns entities that match both\npredicate `foo` and predicate `bar`.\n\nLogical AND and logical OR are supported, for example, `foo OR bar`.\n\nYou can negate a predicate with a `-` or `NOT` prefix. For example, `-name:foo` returns\nall entities with names that don't match the predicate `foo`.\n| Logical operators are not case-sensitive (for example, \"or\" and \"OR\" are acceptable).\n\n### Abbreviated syntax\n\nAn abbreviated search syntax is also available, using `|` for `OR` operators and\n`,` for `AND` operators.\n\nFor example, to search for entries inside one of many projects using the `OR`\noperator, you can use:\n\n`projectid:(pid1|pid2|pid3|pid4)`\n\nInstead of:\n\n`projectid:pid1 OR projectid:pid2 OR projectid:pid3 OR projectid:pid4`\n\nTo search for entries with matching column names:\n\n- AND: `column:(name1, name2, name3)`\n- OR: `column:(name1|name2|name3)`\n\nThis abbreviated syntax works for the [qualified\npredicates](#qualified_predicates) listed earlier, except for `tag`, `term`,\n`policytag`, `policytagid` and `label`."]]
