Methods

getCustomPropertyFilter() (deprecated)

public abstract String getCustomPropertyFilter()

Deprecated. google.cloud.contentwarehouse.v1.DocumentQuery.custom_property_filter is deprecated. See google/cloud/contentwarehouse/v1/filters.proto;l=104

This filter specifies a structured syntax to match against the [PropertyDefinition].[is_filterable][] marked as true. The syntax for this expression is a subset of SQL syntax.

Supported operators are: =, !=, <, <=, >, and >= where the left of the operator is a property name and the right of the operator is a number or a quoted string. You must escape backslash (\\) and quote (\") characters. Supported functions are LOWER([property_name]) to perform a case insensitive match and EMPTY([property_name]) to filter on the existence of a key.

Boolean expressions (AND/OR/NOT) are supported up to 3 levels of nesting (for example, "((A AND B AND C) OR NOT D) AND E"), a maximum of 100 comparisons or functions are allowed in the expression. The expression must be < 6000 bytes in length.

Sample Query: (LOWER(driving_license)="class \"a\"" OR EMPTY(driving_license)) AND driving_years > 10

Returns
Type Description
String

The customPropertyFilter.

getQuery()

public abstract String getQuery()

The query string that matches against the full text of the document and the searchable properties.

The query partially supports Google AIP style syntax. Specifically, the query supports literals, logical operators, negation operators, comparison operators, and functions.

Literals: A bare literal value (examples: "42", "Hugo") is a value to be matched against. It searches over the full text of the document and the searchable properties.

Logical operators: "AND", "and", "OR", and "or" are binary logical operators (example: "engineer OR developer").

Negation operators: "NOT" and "!" are negation operators (example: "NOT software").

Comparison operators: support the binary comparison operators =, !=, <, >, <= and >= for string, numeric, enum, boolean. Also support like operator ~~ for string. It provides semantic search functionality by parsing, stemming and doing synonyms expansion against the input query.

To specify a property in the query, the left hand side expression in the comparison must be the property ID including the parent. The right hand side must be literals. For example: "\"projects/123/locations/us\".property_a < 1" matches results whose "property_a" is less than 1 in project 123 and us location. The literals and comparison expression can be connected in a single query (example: "software engineer \"projects/123/locations/us\".salary > 100").

Functions: supported functions are LOWER([property_name]) to perform a case insensitive match and EMPTY([property_name]) to filter on the existence of a key.

Support nested expressions connected using parenthesis and logical operators. The default logical operators is AND if there is no operators between expressions.

The query can be used with other filters e.g. time_filters and folder_name_filter. They are connected with AND operator under the hood.

The maximum number of allowed characters is 255.

string query = 1;

Returns
Type Description
String

The query.
