Searches Data Catalog for multiple resources like entries, tags that match a query.
This does not return the complete resource, only the resource identifier and high level fields.
Clients can subsequently call ``Get`` methods.
Note that searches do not have full recall. There may be results that match your query but are not
returned, even in subsequent pages of results. These missing results may vary across repeated calls to
search. Do not rely on this method if you need to guarantee full recall.
:param scope: Required. The scope of this search request.
If a dict is provided, it must be of the same form as the protobuf message
:class:`~google.cloud.datacatalog_v1beta1.types.Scope`
:param query: Required. The query string in search query syntax. The query must be non-empty.
Query strings can be simple as "x" or more qualified as:
- name:x
- column:x
- description:y
Note: Query tokens need to have a minimum of 3 characters for substring matching to work
correctly. See `Data Catalog Search Syntax <https://cloud.google.com/data-catalog/docs/how-
to/search-reference>`__ for more information.
:param page_size: The maximum number of resources contained in the underlying API response. If page
streaming is performed per-resource, this parameter does not affect the return value. If page
streaming is performed per-page, this determines the maximum number of resources in a page.
:param order_by: Specifies the ordering of results, currently supported case-sensitive choices are:
- ``relevance``, only supports descending
- ``last_access_timestamp [asc|desc]``, defaults to descending if not specified
- ``last_modified_timestamp [asc|desc]``, defaults to descending if not specified
If not specified, defaults to ``relevance`` descending.
